Title: Extra whitespace error Last modified: September 18, 2025 --- # Extra whitespace error * Resolved [jelux](https://wordpress.org/support/users/jelux/) * (@jelux) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/extra-whitespace-error/) * Hi, the UpdraftPlus Backup plugin is giving me a strange error. * Warning: Your WordPress installation has a problem with emitting extra whitespace. This could corrupt backups downloaded from here. Follow this link for more information. * Following what’s written on this link, I tried deactivating all the plugins and activating them one at a time, and it seems that the plugin generating the error is WP-Optimize. Is this possible? I’ve attached a link to a GIF. * [https://drive.google.com/drive/folders/1xitB9rSGUfg8JzWW-vg3ZL37BjvCSRbt?usp=sharing](https://drive.google.com/drive/folders/1xitB9rSGUfg8JzWW-vg3ZL37BjvCSRbt?usp=sharing) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Support [vupdraft](https://wordpress.org/support/users/vupdraft/) * (@vupdraft) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/extra-whitespace-error/#post-18647451) * Can you post your php error log using a tool such as pastebin.com? - This reply was modified 8 months, 3 weeks ago by [threadi](https://wordpress.org/support/users/threadi/). - This reply was modified 8 months, 3 weeks ago by [Jan Dembowski](https://wordpress.org/support/users/jdembowski/).

You can try the following to resolve the whitespace error.1. Check your theme’s functions.php file for any custom code you might have added. Also check custom code snippets, if any is in use on your site.2. Temporarily switch to a default WP theme to see if anything changes.3. Update your theme and plugins to fix lingering errors.4. Disable all other plugins and enable them one after the other, checking in each case which one triggers the error. * Let us know if any of that helps. * Regards. * Thread Starter [jelux](https://wordpress.org/support/users/jelux/) * (@jelux) * [8 months, 1 week ago](https://wordpress.org/support/topic/extra-whitespace-error/page/2/#post-18663436) * Hi, it seems that the problem is related to when I put the site in maintenance mode, I don’t know why, for the moment it seems that when I exit maintenance mode the message doesn’t appear * Plugin Support [vupdraft](https://wordpress.org/support/users/vupdraft/) * (@vupdraft) * [8 months, 1 week ago](https://wordpress.org/support/topic/extra-whitespace-error/page/2/#post-18665759) * Thank you for this, I will have a go at replicating this and if I can, I will pass it onto our development team Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Extra whitespace error’ is closed to new replies. * ![](https://ps.w.org/wp-optimize/assets/icon-256x256.png?rev=1552899) * [WP-Optimize – Cache, Compress images, Minify & Clean database to boost page speed & performance](https://wordpress.org/plugins/wp-optimize/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-optimize/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-optimize/) * [Active Topics](https://wordpress.org/support/plugin/wp-optimize/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-optimize/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-optimize/reviews/) * 18 replies * 4 participants * Last reply from: [vupdraft](https://wordpress.org/support/users/vupdraft/) * Last activity: [8 months, 1 week ago](https://wordpress.org/support/topic/extra-whitespace-error/page/2/#post-18665759) * Status: resolved
