Conflict with WP Front User plugin

Hi @musicasara

Many thanks to you!

I’ve right now tested WP Frontend User version 3.5.29 with the last version of Freesoul Deactivate Plugins 1.9.3.3, but I have no issues.
Just to be sure, I’ve tested this plugin: https://ww.wp.xz.cn/plugins/wp-user-frontend/, is it the right plugin?

Probably, it depends on the settings of WP Frontend User, or a third plugin together with WP Frontend User triggers the issue.

Be sure you have the last version of FDP. If so, when a plugin triggers a fatal error in the backend, FDP automatically deactivates it on all the FDP backend pages. So I suppose it’s not a fatal error that is giving problems to the FDP backend pages, but something else. But you need to be sure you have FDP v. 1.9.3.3.

If you already have v. 1.9.3.3, I suggest you inspect elements and check if you have red errors in the console (right-click => Inspect => Console).
If you see any errors, please, copy/paste them or share a screenshot.

Check also if you have some PHP warnings. To check the warnings add this code in wp-config.php before the comment /* That’s all, stop editing! Happy publishing. */:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

Then visit again the FDP backend pages, and check the file wp-content/debug.log.
Let me know if you find something in wp-content/debug.log.

Have a great day!

Jose
