Title: Cannot open PDF file Last modified: January 16, 2022 --- # Cannot open PDF file * Resolved [Gerard Blanco](https://wordpress.org/support/users/sixaxis/) * (@sixaxis) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/) * Hi there, * I’m not sure after what update this happened (WordPress? WooCommerce? WooCommerce PDF Invoices & Packing Slips?), but now every time I create a PDF, the browser shows this: [https://i.imgur.com/HRvYi5K.png](https://i.imgur.com/HRvYi5K.png) * I have followed the steps [here](https://wordpress.org/support/topic/read-this-first-9/): everything is green, the error also appears with the default template, I’ve got enough memory (128M) and I don’t see any error after activating “Enable debug output” (I don’t know where I should look at, actually). * Could you help me troubleshoot this, please? Thanks! * Here you have the info from the Site Health menu. * ``` ### wp-core ### version: 5.8.3 site_language: he_IL user_language: he_IL timezone: Asia/Jerusalem permalink: /%postname%/ https_status: true multisite: false user_registration: 1 blog_public: 1 default_comment_status: undefined environment_type: production user_count: 17 dotorg_communication: true ### wp-paths-sizes ### wordpress_path: ****** wordpress_size: loading... uploads_path: ****** uploads_size: loading... themes_path: ****** themes_size: loading... plugins_path: ****** plugins_size: loading... database_size: loading... total_size: loading... ### wp-dropins (2) ### maintenance.php: true object-cache.php: true ### wp-active-theme ### name: Blocksy Child (blocksy-child) version: undefined author: Creative Themes author_website: (undefined) parent_theme: Blocksy (blocksy) theme_features: core-block-patterns, widgets-block-editor, post-thumbnails, automatic-feed-links, responsive-embeds, html5, title-tag, custom-logo, lifterlms-sidebars, boostify-header-footer, fl-theme-builder-headers, fl-theme-builder-footers, fl-theme-builder-parts, editor-gradient-presets, editor-color-palette, menus, align-wide, customize-selective-refresh-widgets, header-footer-elementor, woocommerce, wc-product-gallery-lightbox, widgets theme_path: ****** auto_update: כיבוי ### wp-parent-theme ### name: Blocksy (blocksy) version: 1.8.14 author: CreativeThemes author_website: https://creativethemes.com theme_path: ****** auto_update: כיבוי ### wp-themes-inactive (3) ### Twenty Nineteen: version: 2.1, author: צוות וורדפרס, עדכונים אוטומטיים מושבתים Twenty Twenty: version: 1.8, author: צוות וורדפרס, עדכונים אוטומטיים מושבתים Twenty Twenty-One: version: 1.4, author: צוות וורדפרס, עדכונים אוטומטיים מושבתים ### wp-mu-plugins (1) ### Gerard's plugin: version: 1.0, author: Gerard Blanco ### wp-plugins-active (32) ### Admin Menu Editor Pro: version: 2.16, author: Janis Elsts (latest version: 2.16.1), עדכונים אוטומטיים מושבתים Blocksy Companion (Premium): version: 1.8.16, author: CreativeThemes, עדכונים אוטומטיים מושבתים CAOS: version: 4.1.9, author: Daan from FFW.Press (latest version: 4.2.1), עדכונים אוטומטיים מושבתים Cities Shipping Zones for WooCommerce: version: 1.1.5, author: Condless, עדכונים אוטומטיים מושבתים Disable WooCommerce Bloat: version: 2.6.1, author: ospiotr, עדכונים אוטומטיים מושבתים Easy WP SMTP: version: 1.4.7, author: wpecommerce, alexanderfoxc, עדכונים אוטומטיים מושבתים Enable Media Replace: version: 3.6.3, author: ShortPixel, עדכונים אוטומטיים מושבתים Fluent Forms: version: 4.2.21, author: Contact Form -

Do you get a PDF in your email or is that the PDF doesn’t get generated at all? * Plugin Contributor [dwpriv](https://wordpress.org/support/users/dwpriv/) * (@dwpriv) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15265519) * Gerard, * It appears you’re using the MPDF addon, which is likely causing the error. We’d recommend you use the updated version first and take it from there. [Get it here.](https://github.com/wpovernight/woocommerce-pdf-ips-mpdf/releases/tag/v2.3.0) * Thread Starter [Gerard Blanco](https://wordpress.org/support/users/sixaxis/) * (@sixaxis) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15266963) * Hi [@dwpriv](https://wordpress.org/support/users/dwpriv/), * Thanks for replying. I updated the plugin (thanks for that!), but the issue is still there. If I try to save the PDF, I can see that is 0 bytes, so it looks like there is an issue with the generation. * If it helps, if I try to add the &output=html, then it works well, although looks more unstyled, for example I get no logo. * Thanks! * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15267946) * Could you navigate to **WooCommerce > Status > Logs** and check for logs named` woocommerce-pdf-ips-mpdf-xxx` and check for errors there? * Thread Starter [Gerard Blanco](https://wordpress.org/support/users/sixaxis/) * (@sixaxis) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15270979) * Hi [@pomegranate](https://wordpress.org/support/users/pomegranate/), * Sure, there’s a lot of these errors: * ``` 2022-01-19T09:49:13+00:00 CRITICAL Error detected. PDF file generation aborted: imagecreatefromstring(): gd-png: libpng warning: iCCP: known incorrect sRGB profile ``` * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15271484) * Thanks, that helps. It seems this is probably related not to a plugin update but a PHP update. Can you try to swap your logo by a JPG version (the error tells me it’s PNG at the moment), enable “Test mode” and test to see if you can generate the PDF now? * Thread Starter [Gerard Blanco](https://wordpress.org/support/users/sixaxis/) * (@sixaxis) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15276700) * Thanks [@pomegranate](https://wordpress.org/support/users/pomegranate/)! * Now it works well. Can I disable “Test mode” or do you need me to do something else? * Plugin Contributor [Ewout](https://wordpress.org/support/users/pomegranate/) * (@pomegranate) * [4 years, 4 months ago](https://wordpress.org/support/topic/cannot-open-pdf-file/#post-15276710) * It depends – all existing invoices will still link to the old PNG logo. You can either open them again with test mode enabled (just once is enough to set it to “JPG”) or enable “Always use the most current settings”.
