Title: Code Errors when deactivating the plugin Last modified: April 8, 2020 --- # Code Errors when deactivating the plugin * Resolved [michaeljb](https://wordpress.org/support/users/michaeljb/) * (@michaeljb) * [5 years, 12 months ago](https://wordpress.org/support/topic/code-errors-when-deactivating-the-plugin/) * Hi there, i have just taken over the management of a site. I have a theme conflict somewhere and i am trying find out if its a plugin that is causing the issue. So i disabled all plugins to see if i could isolate which plugin it was, as soon as i deactivated BACKwpup, the whole site crashed. When you navigated to the site I received these errors messages ( below ) luckily i was able to get back in the backend via a WP recovery link and enable the plugin again and the site came back online. Can you please let me know what the issue is and why this is happening as i should be able to deactivate plugins on a site without the site crashing. Thanks for you time * Fatal error: Uncaught Error: Class ‘BackWPup_Admin’ not found in /home/ifmatoro/ public_html/wp-content/themes/ifma/includes/profile-clean-up.php:43 Stack trace:# 0 /home/ifmatoro/public_html/wp-content/themes/ifma/functions.php(256): include()# 1 /home/ifmatoro/public_html/wp-settings.php(497): include(‘/home/ifmatoro/…’)# 2 /home/ifmatoro/public_html/wp-config.php(90): require_once(‘/home/ifmatoro/…’)# 3 /home/ifmatoro/public_html/wp-load.php(37): require_once(‘/home/ifmatoro/…’)# 4 /home/ifmatoro/public_html/wp-blog-header.php(13): require_once(‘/home/ifmatoro/…’)# 5 /home/ifmatoro/public_html/index.php(17): require(‘/home/ifmatoro/…’) #6 {main} thrown in /home/ifmatoro/public_html/wp-content/themes/ifma/includes/profile- clean-up.php on line 43 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcode-errors-when-deactivating-the-plugin%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 4 replies - 1 through 4 (of 4 total) * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [5 years, 12 months ago](https://wordpress.org/support/topic/code-errors-when-deactivating-the-plugin/#post-12650660) * [@michaeljb](https://wordpress.org/support/users/michaeljb/) hmm can you just remove the BackWPUp plugin then install it again, look like there is missing files in there? * Thread Starter [michaeljb](https://wordpress.org/support/users/michaeljb/) * (@michaeljb) * [5 years, 12 months ago](https://wordpress.org/support/topic/code-errors-when-deactivating-the-plugin/#post-12650850) * i can’t as when you deactivate the plugin the site crashes and the above error displays when you type the url in or try to load the backend. * When this happened the first time, the plugin was deleted from the c\panel file manager and i was able to login to the backend from the WP recovery link, I installed the app again from there and the site came back up.. So i have actually installed it again and it still makes no difference. * Is there anyway to ftp the missing files to the appropriate plugin folders which would fix this? or any other ideas please? * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [5 years, 12 months ago](https://wordpress.org/support/topic/code-errors-when-deactivating-the-plugin/#post-12656387) * [@michaeljb](https://wordpress.org/support/users/michaeljb/) hmm so can you just temporary switch to a default WordPress theme, I saw there is an error caused by your current theme: `Fatal error: Uncaught Error: Class ‘BackWPup_Admin’ not found in /home/ifmatoro/public_html/wp-content/themes/ifma/includes/profile-clean- up.php:43` * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [5 years, 11 months ago](https://wordpress.org/support/topic/code-errors-when-deactivating-the-plugin/#post-12689207) * [@michaeljb](https://wordpress.org/support/users/michaeljb/) * since we haven’t heard back from you, I’m going to mark it as resolved.
