In the admin section of the website nearly all of the pages are working fine except for when i try to edit certain attributes on my products such as cetgories, upsells, cross sells etc.
I can make new products, add images etc but not select a category.
When I try to select a category i get a page ( as below that comes up blank with only the title from the left sidebar - Product Information)
Does anyone have any ideas on how to fix this - I’ve spent all day messing around and got nowhere?
Help would be really appreciated please.
