Resolve WordPress wp-admin/edit.php Page 500 & 404 Error for Admin Posts Link

If you get WordPress page not found error or 500 internal server error for opening admin/edit.php Admin Panel Posts Link, you need to disable mod_security on your server.

To disable mod_security, open your blog .htacess which is stored at the root of the site from public_html folder or inside wordpress/ folder.

 
# 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

And add the following to the start of your .htaccess file:

 
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterPost Off
</IfModule>

Save the .htaccess file and upload it again to the same public_html folder replacing the original htaccess file on server.

Hope that helps.

Cheers.
