That is most likely from a mod you have installed.
Ok lets do this, disable plugins via the
includes/config.php file.
To do that open your
includes/config.php file and below
<?php add the following.
PHP Code:
define('DISABLE_HOOKS', true);
So it looks like this:
PHP Code:
<?php
define('DISABLE_HOOKS', true);

Use a editor like
notepad++ to edit any files,
don't use Notepad or Wordpad.
If that fixes the issue enable plugins again by adding
// before the line you added, then navigate to
ACP --> Plugins & Products --> Manage Products and disable one mod at a time until you find the one causing the issue.
Once you find the culprit, post in that mods thread what the issue is, and maybe someone in that thread can help.
