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?
