Every plugin causes 500 server error

    Hello, I’ve recently upgraded wordpress and I have this very weird problem. I have 16 plugins activated at the moment – and whenever I activate a new one, the whole site goes down and gives me a 500 error. It doesn’t matter which plugin. When I disable 2 plugins and randomly activate a new one to keep the numebr at 16, it just works. This is very strange and as it’s not related to a specific plugin, I don’t know how to fix this. Any help would be much appreciated.

    Internal server errors (error 500) are often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the default theme for your version of WordPress to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your SFTP or FTP client to view invisible files.

    If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.

    I guess this is an automated reply as my problem has nothing to do with this. Could you please read my post? I’ve already tried disabling all plugins and editing the htaccess file. The problem is NOT related to a specific plugin. Any plugin causes this.

    Check your error logs to see if you can find a reason for the 500 error and ask your host to check theirs, too. 500 errors are “something bad happened” and they’re logged.

    And, by the way, t-p’s reply included:
