Title: Uncaught Error: Call to undefined function Nextend\Framework\Font\n Last modified: April 27, 2021 --- # Uncaught Error: Call to undefined function Nextend\Framework\Font\n * Resolved [bonovski](https://wordpress.org/support/users/bonovski/) * (@bonovski) * [5 years, 1 month ago](https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-nextendframeworkfontn/) * I have a rather curious problem on one of my local development sites. Running WP 5.7.1 on the latest laravel valet@macos. I have to add that the error presents itself only on this particular wp install. Multiple other work without a problem in the same environment. * ``` Fatal error: Uncaught Error: Call to undefined function Nextend\Framework\Font\n2_x() in /Users/bonovski/Sites/staging/wp-content/plugins/smart-slider-3/Nextend/Framework/Font/FontSettings.php on line 30 Call stack: Nextend\F\F\FontSettings::load() wp-content/plugins/smart-slider-3/Nextend/Framework/Font/FontSettings.php:23 Nextend\F\F\FontSettings::__construct() wp-content/plugins/smart-slider-3/Nextend/Framework/Font/FontSettings.php:138 require() wp-content/plugins/smart-slider-3/Nextend/Autoloader.php:194 Nextend\Autoloader::requireFile() wp-content/plugins/smart-slider-3/Nextend/Autoloader.php:175 Nextend\Autoloader::loadMappedFile() wp-content/plugins/smart-slider-3/Nextend/Autoloader.php:128 Nextend\Autoloader::loadClass() spl_autoload_call() wp-content/plugins/smart-slider-3/Nextend/Framework/Font/Sources/GoogleFonts/GoogleFonts.php:119 Nextend\F\F\S\G\GoogleFonts::onFontManagerLoad() wp-content/plugins/smart-slider-3/Nextend/Framework/Font/FontSources.php:44 Nextend\F\F\FontSources::onFontManagerLoad() wp-content/plugins/smart-slider-3/Nextend/Framework/Asset/Predefined.php:65 Nextend\F\A\Predefined::frontend() wp-content/plugins/smart-slider-3/Nextend/Framework/Controller/AbstractController.php:125 Nextend\F\C\AbstractController::initialize() wp-content/plugins/smart-slider-3/Nextend/Framework/Controller/AbstractController.php:50 Nextend\F\C\AbstractController::__construct() wp-content/plugins/smart-slider-3/Nextend/SmartSlider3/Application/Frontend/ApplicationTypeFrontend.php:24 Nextend\S\A\F\ApplicationTypeFrontend::getControllerSlider() call_user_func() wp-content/plugins/smart-slider-3/Nextend/Framework/Application/AbstractApplicationType.php:106 Nextend\F\A\AbstractApplicationType::getController() wp-content/plugins/smart-slider-3/Nextend/Framework/Application/AbstractApplicationType.php:86 Nextend\F\A\AbstractApplicationType::process() wp-content/plugins/smart-slider-3/Nextend/SmartSlider3/Platform/WordPress/Shortcode/Shortcode.php:319 Nextend\S\P\W\S\Shortcode::render() wp-content/plugins/smart-slider-3/Nextend/SmartSlider3/Platform/WordPress/Shortcode/Shortcode.php:189 Nextend\S\P\W\S\Shortcode::doShortcode() wp-includes/shortcodes.php:343 do_shortcode_tag() preg_replace_callback() wp-includes/shortcodes.php:218 do_shortcode() wp-content/themes/test/parts/front/front-slider.php:10 require() wp-includes/template.php:732 load_template() wp-includes/template.php:676 locate_template() wp-includes/general-template.php:204 get_template_part() wp-content/themes/test/front-page.php:10 include() wp-includes/template-loader.php:106 require_once() wp-blog-header.php:19 require() index.php:17 require() /Users/bonovski/.composer/vendor/laravel/valet/server.php:219 ``` - This topic was modified 5 years, 1 month ago by [bonovski](https://wordpress.org/support/users/bonovski/). - This topic was modified 5 years, 1 month ago by [bonovski](https://wordpress.org/support/users/bonovski/).

So please, delete your current Smart Slider 3 installation, then install it again from WordPress > Plugins > Add new > and type in Smart Slider 3 into the “Search plugins” field. * Then check if the problem still occurs. If it does, then could you check please if you navigate to here: - \wp-content\plugins\smart-slider-3\Nextend\Framework\Localization\ * can you see the file there called “Functions.php” if you do, please open it and check if it has any content and contains the function n2_x function or not: ` function n2_x($text, $context, $domain = 'nextend') {...}` * Best regards, Laszlo. * Thread Starter [bonovski](https://wordpress.org/support/users/bonovski/) * (@bonovski) * [5 years, 1 month ago](https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-nextendframeworkfontn/#post-14370858) * Thanks for the quick response, I did delete it a few times already and installed from scratch, disabled all plugins except for smart-slider-3, no luck. * I also enabled troubleshoot mode in WP and tried to activate just ss3 and it wouldn’t let me: * `When enabling the plugin, smart-slider-3, a site failure occurred. Because of this the change was automatically reverted.` * The Functions.php file is present, as well as the function: * ``` function n2_x($text, $context, $domain = 'nextend') { $translations = Localization::getTranslationsForDomain($domain); return $translations->translate($text, $context); } ``` * My debug log: * ``` Smart Slider 3 - version: 3.4.1.17/b:release-3.4.1.17/r:821e0c40c1a68904613c085ca8d654d9473341fb Plan: free Platform: WordPress - 5.7.1 Site url: //staging.test/ Path: /Users/bonovski/Sites/staging/wp-content Uri: https://staging.test/wp-content Browser: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.85 Safari/537.36 PHP: 7.4.16 PHP - memory_limit: 512M PHP - max_input_vars: 1000 PHP - opcache.enable: 1 PHP - opcache.revalidate_freq: 2 No conflicts detected Path to uri: /Users/bonovski/Sites/staging => https://staging.test /Users/bonovski/Sites/staging/wp-content => https://staging.test/wp-content /Users/bonovski/Sites/staging/wp-content/plugins => https://staging.test/wp-content/plugins /Users/bonovski/Sites/staging/wp-content/uploads => https://staging.test/wp-content/uploads wp_upload_dir() => path: /Users/bonovski/Sites/staging/wp-content/uploads/2021/04 url: https://staging.test/wp-content/uploads/2021/04 subdir: /2021/04 basedir: /Users/bonovski/Sites/staging/wp-content/uploads baseurl: https://staging.test/wp-content/uploads error: <= Theme: test is version 2.0.0 Activated Plugins: - acf-content-analysis-for-yoast-seo/yoast-acf-analysis.php - 3.0.1 - ACF Content Analysis for Yoast SEO - advanced-custom-fields-pro/acf.php - 5.9.5 - Advanced Custom Fields PRO - wc-aelia-foundation-classes/wc-aelia-foundation-classes.php - 2.1.6.210406 - Aelia Foundation Classes for WooCommerce - woo-checkout-field-editor-pro/checkout-form-designer.php - 1.4.8 - Checkout Field Editor for WooCommerce - font-awesome/index.php - 4.0.0-rc22 - Font Awesome - foobox-image-lightbox/foobox-free.php - 2.7.16 - FooBox Image Lightbox - foogallery/foogallery.php - 2.0.24 - FooGallery - gdpr-cookie-compliance/moove-gdpr.php - 4.5.2 - GDPR Cookie Compliance (CCPA, PIPEDA ready) - health-check/health-check.php - 1.4.5 - Health Check & Troubleshooting - members/members.php - 3.1.5 - Members - checkout-fees-for-woocommerce/checkout-fees-for-woocommerce.php - 2.6.2 - Payment Gateway Based Fees and Discounts for WooCommerce - polylang-wc/polylang-wc.php - 1.5.4 - Polylang for WooCommerce - polylang-pro/polylang.php - 3.0.4 - Polylang Pro - query-monitor/query-monitor.php - 3.6.7 - Query Monitor - regenerate-thumbnails/regenerate-thumbnails.php - 3.1.5 - Regenerate Thumbnails - show-current-template/show-current-template.php - 0.4.5 - Show Current Template - smart-slider-3/smart-slider-3.php - 3.4.1.17 - Smart Slider 3 - tablepress/tablepress.php - 1.13 - TablePress - tablepress-responsive-tables/tablepress-responsive-tables.php - 1.8 - TablePress Extension: Responsive Tables - under-construction-page/under-construction.php - 3.88 - Under Construction - updraftplus/updraftplus.php - 1.16.53 - UpdraftPlus - Backup/Restore - woocommerce/woocommerce.php - 5.2.2 - WooCommerce - woocommerce-bankart-payment-gateway/woocommerce-bankart-payment-gateway.php - 1.7.3.2 - WooCommerce Bankart Payment Gateway Extension - woocommerce-eu-vat-assistant/woocommerce-eu-vat-assistant.php - 2.0.14.210317 - WooCommerce EU VAT Assistant - wp-optimize/wp-optimize.php - 3.1.8 - WP-Optimize - Clean, Compress, Cache - wp-migrate-db/wp-migrate-db.php - 1.0.17 - WP Migrate DB - wordpress-seo/wp-seo.php - 16.1.1 - Yoast SEO - wordpress-seo-premium/wp-seo-premium.php - 16.1 - Yoast SEO Premium NOT Activated Plugins: - autoptimize/autoptimize.php - 2.8.3 - Autoptimize - wordfence/wordfence.php - 7.5.2 - Wordfence Security - wp-super-cache/wp-cache.php - 1.7.2 - WP Super Cache ``` * Plugin Support [Gabor](https://wordpress.org/support/users/nextendweb_gabor/) * (@nextendweb_gabor) * [5 years, 1 month ago](https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-nextendframeworkfontn/#post-14371000) * Hi [@bonovski](https://wordpress.org/support/users/bonovski/)! * This still looks like as if for some reason not all our files would be able to load. Like a file, which suppose to load the Functions.php couldn’t load, for example it is missing or there is server cache, which still load a previous version of the PHP files instead of the latest ones, or another server created limitation happens. Could you please try to upload the files this way: [https://smartslider.helpscoutdocs.com/article/1717-wordpress-installation#ftp](https://smartslider.helpscoutdocs.com/article/1717-wordpress-installation#ftp) by moving the folder and files manually? You can just let them overwrite the files what you already have there. This could be better, because sometimes servers aren’t moving all files as they should be. * If you will still have a problem after this, please create a PHP file with this code in it: * ``` ``` * take a look at it in your browser -> right click and download the page, then send it to us in a zip file, to [support@nextendweb.com](https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-nextendframeworkfontn/support@nextendweb.com?output_format=md) and we will try to figure out what could be wrong. * Thread Starter [bonovski](https://wordpress.org/support/users/bonovski/) * (@bonovski) * [5 years, 1 month ago](https://wordpress.org/support/topic/uncaught-error-call-to-undefined-function-nextendframeworkfontn/#post-14371333) * I copied the files manually, but unfortunately that didn’t help. * I also spun up a docker environment with apache as the web server and the same error happened. * I deleted as much as possible from the installation including various caches etc. * I just sent you the phpinfo result.
