Hi Sylvain
do you mean “after deactivating Freesoul Deactivate Plugins the website gives the error ERR_TOO_MANY_REDIRECTS”?
If so, be sure there isn’t the file wp-content/mu-plugins/eos-deactivate-plugins.php. When you deactivate FDP it automatically deletes that file, but if for any unexpected reasons that file was not deleted, the code of that file still runs.
If on the contrary, you don’t see that file, it means that Freesoul Deactivate Plugins has nothing to do with this issue, because without that file, if FDP is deactivated, no lines of code of FDP run. It doesn’t write anything in .htaccess, and doesn’t do anything that after deactivation may cause redirections.
When you have this kind of problem it means your website redirects to an URL that redirects to the same URL creating an infinite loop of redirections.
You may have problems with redirections from https://www.yoursite.com to yoursite.com or the contrary, or from https://yoursite.com to https://yoursite.com.
Or maybe another kind of redirection that was working until FDP was deactivating a specific plugin, and now that it doesn’t deactivate anymore that plugin, you have the issue.
Or maybe, you have an issue with the rewrite rules. This is maybe the most probable cause. In this case, just go to Settings => Permalinks. By doing this, you will refresh the rewrite rules, and this may be enough to solve the issue.
I hope it helps.
Have a great day
Jose
