Title: PHP 7.4 Errors Last modified: August 10, 2020 --- # PHP 7.4 Errors * Resolved [Jeremy Nusser](https://wordpress.org/support/users/nusserstudios/) * (@nusserstudios) * [5 years, 9 months ago](https://wordpress.org/support/topic/php-7-4-errors/) * I just upgraded Roots Trellis to PHP 7.4, and I’m getting PHP errors with PHP 7.4. It uses composer to manage plugins. I have uninstalled and reinstalled it and even bumped it from version 8.8 to 8.8.1. This is what I get back: * Notice: Trying to access array offset on value of type bool in /srv/www/example. com/current/web/app/plugins/jetpack/modules/theme-tools/social-menu.php on line 66 Call Stack # Time Memory Function Location 1 0.0005 394976 {main}( ) …/index. php:0 2 0.0013 396464 require( ‘/srv/www/example.com/current/web/wp/wp-blog-header. php’ ) …/index.php:5 3 0.0018 407616 require_once( ‘/srv/www/example.com/current/ web/wp/wp-load.php’ ) …/wp-blog-header.php:13 4 0.0024 408984 require_once( ‘/ srv/www/example.com/current/web/wp-config.php’ ) …/wp-load.php:42 5 0.0318 976144 require_once( ‘/srv/www/example.com/current/web/wp/wp-settings.php’ ) …/wp-config. php:9 6 0.9824 62669400 do_action( ) …/wp-settings.php:518 7 0.9824 62671056 WP_Hook->do_action( ) …/plugin.php:478 8 0.9824 62671056 WP_Hook->apply_filters()…/ class-wp-hook.php:311 9 0.9907 63333664 jetpack_social_menu_init( ) …/class-wp- hook.php:287 10 0.9908 63334360 jetpack_social_menu_get_type( ) …/social-menu. php:47 * ( ! ) Notice: wp_woocommerce_session_4c0809f8f852faacbbf1e8172a0a7040 cookie cannot be set – headers already sent by /srv/www/example.com/current/web/app/ plugins/jetpack/modules/theme-tools/social-menu.php on line 66 in /srv/www/example. com/current/web/app/plugins/woocommerce/includes/wc-core-functions.php on line 1038 Call Stack # Time Memory Function Location 1 0.0005 394976 {main}( ) …/ index.php:0 2 0.0013 396464 require( ‘/srv/www/example.com/current/web/wp/wp- blog-header.php’ ) …/index.php:5 3 1.2493 73094728 wp( ) …/wp-blog-header.php: 16 4 1.2493 73094760 WP->main( ) …/functions.php:1274 5 1.2542 73311112 do_action_ref_array()…/ class-wp.php:752 6 1.2542 73311112 WP_Hook->do_action( ) …/plugin.php:544 7 1.2542 73311112 WP_Hook->apply_filters( ) …/class-wp-hook.php:311 8 1.2549 73241424 WC_Gateway_PPEC_Cart_Handler->ensure_session( ) …/class-wp-hook.php:287 9 1.2549 73241424 WC_Session_Handler->set_customer_session_cookie( ) …/class-wc-gateway- ppec-cart-handler.php:603 10 1.2550 73241696 wc_setcookie( ) …/class-wc-session- handler.php:135 11 1.2550 73242144 trigger_error ( ) …/wc-core-functions.php: 1038 * ( ! ) Notice: Trying to access array offset on value of type bool in /srv/www/ example.com/current/web/app/plugins/jetpack/modules/theme-tools/social-menu.php on line 66 Call Stack # Time Memory Function Location 1 0.0005 394976 {main}()…/ index.php:0 2 0.0013 396464 require( ‘/srv/www/example.com/current/web/wp/wp- blog-header.php’ ) …/index.php:5 3 1.2559 73252608 require_once( ‘/srv/www/example. com/current/web/wp/wp-includes/template-loader.php’ ) …/wp-blog-header.php:19 4 1.2612 73404840 include( ‘/srv/www/example.com/current/web/app/themes/example- theme/page-templates/home-template.php’ ) …/template-loader.php:106 5 1.2612 73404840 get_header( ) …/home-template.php:10 6 1.2612 73405968 locate_template()…/ general-template.php:41 7 1.2613 73406064 load_template( ) …/template.php:672 8 1.2617 73420224 require_once( ‘/srv/www/example.com/current/web/app/themes/ example-theme/header.php’ ) …/template.php:723 9 1.2623 73428712 wp_head( ) …/ header.php:20 10 1.2623 73428712 do_action( ) …/general-template.php:2884 11 1.2623 73429088 WP_Hook->do_action( ) …/plugin.php:478 12 1.2623 73429088 WP_Hook- >apply_filters( ) …/class-wp-hook.php:311 13 1.2631 73437032 wp_enqueue_scripts()…/ class-wp-hook.php:287 14 1.2631 73437032 do_action( ) …/script-loader.php:2294 15 1.2631 73437408 WP_Hook->do_action( ) …/plugin.php:478 16 1.2631 73437408 WP_Hook->apply_filters( ) …/class-wp-hook.php:311 17 1.8055 73792688 jetpack_social_menu_style()…/ class-wp-hook.php:287 18 1.8055 73792688 jetpack_social_menu_get_type( ) …/social- menu.php:76 Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Author [Brandon Kraft](https://wordpress.org/support/users/kraftbj/) * (@kraftbj) * Code Wrangler * [5 years, 9 months ago](https://wordpress.org/support/topic/php-7-4-errors/#post-13234410) * Thanks for the report! It looks like something on your site is causing the `jetpack- social-menu` theme support value to return something a bit unexpected by us. * I’ve opened a bug report and code fix at [https://github.com/Automattic/jetpack/pull/16795](https://github.com/Automattic/jetpack/pull/16795) that would resolve this. * It is currently slated to be reviewed and included in the Jetpack 8.9 release, scheduled for the first week of September. * Thanks for letting us know! * Thread Starter [Jeremy Nusser](https://wordpress.org/support/users/nusserstudios/) * (@nusserstudios) * [5 years, 9 months ago](https://wordpress.org/support/topic/php-7-4-errors/#post-13237551) * Awesome, thank you Brandon! * [manwithgills](https://wordpress.org/support/users/manwithgills/) * (@manwithgills) * [5 years, 6 months ago](https://wordpress.org/support/topic/php-7-4-errors/#post-13663714) * Good day. I wanted to chime in and alert that I am having issues with Jetpack when I upgrade my server to PHP 7.4. My issue initially started when I upgraded and my wife could not connec to our site using the Woocommerce App on IOS. We reached out to Woocommerce and they advised it was a Jetpack issue. I disconnected, reconnected to no avail. I then deactivated and deleted the plugin. Reinstalled it, and it was still giving the same issue, plus our site health tool was showing site not connected.:200. I then went in downgraded my PHP to 7.3 and the connection reestablished. I upgraded to 7.4 and it broke the connection again. * The only solution I have found is to stick with PHP 7.3. * [Bruce (a11n)](https://wordpress.org/support/users/bruceallen/) * (@bruceallen) * Happiness Engineer * [5 years, 6 months ago](https://wordpress.org/support/topic/php-7-4-errors/#post-13669743) * Could you please start your own thread, as per the [Forum Welcome](https://wordpress.org/support/welcome/)?
