What version of vB4 are you running?
What version of PHP are you running?
Does the same behavior happen with all mods disabled?
To temporarily disable all mods:
Open your
includes/config.php file and below<?php add this line:
PHP Code:
define('DISABLE_HOOKS', true);
So it looks like this:
PHP Code:
<?php
define('DISABLE_HOOKS', true);

Once testing is done, you can then remove that line from the includes/config.php file.
