What can cause those two options to not return anything from the WWC admin panel:

Show Server Error Log
Clear the Log to today's date

Clicking on them makes WWC to sit there and not return anything. I have that at an installation site and I am trying to figure out what may cause this.

Everything else is working as is. All the other admin functions work ok. That has been in production since months. But, we just discovered today that those two options do not respond.

Basically, the installation is done to not log any hit in that table. But, that shouldn't be a factor to have the option to fail when we click on it.
