Title: Fatal error: Allowed memory size … after plugin activation Last modified: January 3, 2025 --- # Fatal error: Allowed memory size … after plugin activation * Resolved [daradowp123](https://wordpress.org/support/users/daradowp123/) * (@daradowp123) * [1 year, 3 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-after-plugin-activation/) * Hello to everyoune, I’m trying to restore our webpage after this was hacked last month. Likely I do have an backup. I’ve installed the nevest WP version 6.7.1 manually, by creating a new DB, cleaning all FTP folders, giving new passworts for all accounts and so on. The fully new and empty page is existing.First plugin I want to install and activate is wpvivid plugin. * I do the installation steps from the instruction: Install WPvivid Backup & Migration Plugin 1.Go to your sites admin dashboard.2.Navigate to Plugins Menu and search for WPvivid Backup & Migration.3.Find WPvivid Backup & Migration and click Install Now.4. Click Activate. * After clicking the “Activate” putton I get the folowwing errors and WP administration page is not accesable any more. * **Fatal error**: Allowed memory size of 41943040 bytes exhausted (tried to allocate 69632 bytes) in **…/wp-content/plugins/wpvivid-backuprestore/includes/class-wpvivid- remote-collection.php** on line **15** **Fatal error**: Allowed memory size of 41943040 bytes exhausted (tried to allocate 65536 bytes) in **…/wp-includes/class- wp-user.php** on line **881** * In both errors the allowed memory size is bigger then need to allocate. This is a mystery for me. * When I deactivate the wpvivid plugin during the DB entry or during the FTP folder renaming, then the WP administration page is accesable again. * By installing some another plugins like simple SSL or WP comerce no such error accures. * My provider uses PHP 8.0.1 Apache/2.4.10 (Debian)MySQL-Client-Version: 5.5.62 * I hope you can provide any help or ideas. * Thank you very much for your help. * Dennis * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-allowed-memory-size-after-plugin-activation%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Support [tonyrobins](https://wordpress.org/support/users/tonyrobins/) * (@tonyrobins) * [1 year, 3 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-after-plugin-activation/#post-18224403) * Hello [@daradowp123](https://wordpress.org/support/users/daradowp123/) * We are going to take a look at the issue and get back to you as soon as we can. * All the best, * Plugin Support [tonyrobins](https://wordpress.org/support/users/tonyrobins/) * (@tonyrobins) * [1 year, 3 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-after-plugin-activation/#post-18224434) * Hi [@daradowp123](https://wordpress.org/support/users/daradowp123/) * To help efficiently troubleshoot the issue, would you also send us a debug zip of the site to support(at)wpvivid.com? You can find the debug zip from the Debug tab of the plugin. Please also include a link to this thread to help track the issue. * All the best, * Thread Starter [daradowp123](https://wordpress.org/support/users/daradowp123/) * (@daradowp123) * [1 year, 3 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-after-plugin-activation/#post-18224595) * Hi [@tonyrobins](https://wordpress.org/support/users/tonyrobins/), thanks a lot for the quick answer. Just to clarify – the wpvivid plugin needs to be activated to see any tabs of it. Is it correct? My problem is, when I try to activate the plugin, then I get those errors and I doesn’t have the access to wp-admin. When I rename the plugin folder on FTP I get the access again but without any plugins. Is there another possibility to get this debug zip file? FTP or data base? Here [https://wordpress.org/plugins/wpvivid-backuprestore/](https://wordpress.org/plugins/wpvivid-backuprestore/) i can see some screenshots from the plugin. Do you mean the Logs – tab ? Probably Debug tab is a new name for Logs tab. * Plugin Support [nicholas2019](https://wordpress.org/support/users/nicholas2019/) * (@nicholas2019) * [1 year, 3 months ago](https://wordpress.org/support/topic/fatal-error-allowed-memory-size-after-plugin-activation/#post-18224781) * Hello [@daradowp123](https://wordpress.org/support/users/daradowp123/) , * Increase the PHP memory limit to 256 MB by following [the article](https://www.wpbeginner.com/wp-tutorials/fix-wordpress-memory-exhausted-error-increase-php-memory/).
