tab "images" shows nothing in product page

[grbfst]

Hi all, Since today I have a weird problem where the HTML belonging to the tab "Images" (afbeeldingen in Dutch) does not show. I must admit I have been meddling with backoffice code but have gradually put back all original code, still nothing. Anyone experienced this?

Regards, Marc

I can take a look if you will get me access to the back office.

if everything is back to stock, try deleting cache/class_index.php
