File Browser not loading, Editor Plugin gives Internal Server Error

If the File Browser keeps loading forever or Editor Plugin returns “Internal Server Error”, its most likely a file permission issue. Some servers with suPHP are configured so that PHP files that are writable (CHMOD 777) cannot be accessed, giving a 500 Internal Server Error.

To fix this, folder permissions must be set to 0755 and scripts to be 0644 (source)

Run these FTP commands in your wordpress root directory to set the correct permissions:

cd wp-content/plugins
chmod 755 wp-filebase-pro
cd wp-filebase-pro
chmod 644 editor_plugin.php
chmod 644 sync.php
chmod 644 wpfb-ajax.php
chmod 644 wpfb-async-upload.php
chmod 644 wpfb-postbrowser.php
chmod 644 wp-filebase_css.php
chmod 644 wp-filebase_thumb.php

If still no success, try the following:

  • If you still get an Internal Server Error, try 744 instead of 644 for script files.
  • If the File Browser is still not working, make sure your site URL in WordPress settings is set correctly (with our without the www.). Otherwise you might get an “Access-Control-Allow-Origin” error.
  • If you get a forbidden error in the JS console, make sure that script access is not blocked by server configuration. With Apache, their might be access rules in .htaccess files. Check the .htaccess file in your WordPress root, in wp-content and wp-content/plugins . If you don’t know how to identify and remove the access rules, just rename the .htaccess files in wp-content and wp-content/plugins to _.htaccess to disable them.

    I have the probem, that editor_plugin.php is not working, i tried all of this and checked the wp-settings. Some other plugins with buttons in the editor work, some other not.

    Also the select-buttons in the settings of filebase does not work. Any ideas what i can do?

    Thank in advance
    Marco
