Title: Critical error when activated Last modified: November 17, 2021 --- # Critical error when activated * Resolved [chatamelie56](https://wordpress.org/support/users/chatamelie56/) * (@chatamelie56) * [4 years, 5 months ago](https://wordpress.org/support/topic/critical-error-when-activated-2/) * Hi ! when i use the plugin with Oxygen and Divi, it shows me a critical error each time I want to edit a page where I activated Oxygen and not Divi. The websites works in front, it’s the back that doesn’t. Any idea why, please ?

This is just a supposition, but it’s the most frequent cause of fatal errors when you have plugins that depend on other plugins or by the theme. Very probably together with Divi you have a plugin where it’s written the code that can’t be written in the theme. * If this supposition is confirmed, you will solve the problem by disabling also that plugin, and not only Divi. * When a plugin uses a function defined in another plugin or in the theme, it should always first check if that function exists, but sometimes plugin and theme developers forget to check it. * If you need that plugin even if Divi is disabled I will add some code to Freesoul Deactivate Plugins to solve this problem with Divi. * Posting the error will be very helpful to solve this issue. * Thread Starter [chatamelie56](https://wordpress.org/support/users/chatamelie56/) * (@chatamelie56) * [4 years, 5 months ago](https://wordpress.org/support/topic/critical-error-when-activated-2/#post-15081108) * Well I just updated your plugin and, curiously, now it works. Before I had a message saying “a critical error occured, go back to home page” when trying to edit the page where I activated Oxygen. The mysteries of life… Thank you anyway, a lot, for your answer ! If I have the problem again, I’ll come here.

I’m happy you don’t have any more issues.

As soon as we fix this issue, I will be glad to upgrade to the pro version. * The bad part, I can’t see an error message in the log file, however, I do know the critical error from the Version 1.8.8.9.8 Freesoul plugin when active.

For me, it’s totally ok if we continue here, especially if you have the same issue, but be aware that a moderator may delete our comments, if this happens don’t hesitate to open a new thread. * Do you also have Oxygen and Divi? Is the scenario similar to that one described by [@chatamelie56](https://wordpress.org/support/users/chatamelie56/) ? * Are you sure you have the debug enabled in wp-config.php? * Be sure that in your wp-config.php you have * define( ‘WP_DEBUG’, true ); define( ‘WP_DEBUG_LOG’, true ); * Have you received the email from your site about the critical error? * Did it happen on specific pages of the backend or frontend? * For moderators: please write a comment here if you delete our comments maybe explaining why you have delete them. for a few days I have seen my answers disappear without any explanation and the users don’t understand what happens.
