Plugins tab on admin leads to Internal Server Error

    Hi. So I’ve come across a frustrating problem. I’ve scoured these support forums for many solutions that haven’t quite worked for me. Let me recap.

    I had one website running properly thru WP (hosted by Arvixe if that matters) and was tasked with creating another one. It’s up and running, but when I visit the admin tab, I notice two things. One, every time I click the Plugins tab, I get the “Internal Server Error. The server encountered an internal error or misconfiguration” etc…

    Secondly, when I go to the themes tab, the defaults are there, but if I try to add more, nothing loads in the search bar (also an issue when first installing WP thru Softaculous) and the “upload theme” button doesn’t work either. However, if I go to the customize tab, I can upload and activate a theme from there.

    I go to my older website and the same issue. Site is fine and I can post. Themes are there (running Avada which I’ve seen some posters aren’t fond of) but Plugins tab leads to a broken page, basic site plugins like insta/twitter aren’t loading, and I can’t search or add themes from the themes tab.

    I did what many others who’ve posted about this issue over the years have. I deactivated plugins thru phpMyAdmin, I tried to see if .htaccess was corrupt, I went to the default 2015 theme, and I went through all the different permalink settings. Same issue (for both sites). I’m not certain if this issue started when I created the 2nd website (addon domain) so I first tried to reinstall WP and start from scratch then removed it altogether, but still having the issue with my main site.

    I’m led to believe it has to be a permalink issue of some sort where something is redirecting incorrectly, but I’m not terribly well-versed in this field. Anyone have a solution worth trying? I appreciate the help.

    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 FTP or SFTP, 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 FTP or SFTP and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your FTP or SFTP 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.

    Hi Matthew. I was able to resolve the problem. My .htaccess file was indeed messed up. Pasting this:

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    </IfModule>
    # END WordPress

    resolved the issue. I have no idea why every time I start up/reset a new site through Softaculous, the .htaccess file isn’t properly created, but I can again access plugins and themes normally.
