Error 500 on subpanel pagination

Question

Hello.

I have a page with a Detail View and a Subpanel.

Normally, it's like that:

But in the subpanel, if I click on a pagination button to show the remaining items, I get an error in the subpanel:

500 Internal Server Error

Premature end of script headers: index.php

I already set the permissions, done a quick repair, cleaned the cache folder, rebuild the module, but the error persists.

What could be the cause of this error?

Thanks.

Hello Ramon Marcondes,

This can be permissions related so I would recommend making sure that all of your files are owned by the User and Group setup in your apache configuration file. Have you made any recent upgrade or changes to PHP? Do you have FastCGI installed and configured? If so, what happens if you disable it? How about APC caching? Is it installed and if so, what happens if you disable it? These are the most likely candidates to the problem. There may be others but this is a good place to start.

Kind Regards,
