Cannot Access Any Plugin Settings

Please add define( 'WP_DEBUG', true ); to your wp-config.php file and then try to load the page again. See if an error log shows up anywhere on your server. Specifically look in the parent directory of WP, the wp-content directory, the wp-content/plugins directory, and the plugin directory of the plugin in question. Then share the error log with us. If the error log is longer than a few lines please share it using PasteBin.

Get the following error when adding the above code:

This is the file itself:
‘
# BEGIN WordPress
define( ‘WP_DEBUG’, true );
<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

## WP Defender – Prevent information disclosure ##

You did not add it to your wp-config.php file but your .htaccess file.

Please delete it from .htaccess and add it to wp-config.php

DOH! Sorry about that…
