Error loading Associations for Products

[TobyJulien]

HI!

 

Every time i click on associations when editing/adding a product, i get an error: "Tab : Associations (500)

A server error occurred while loading the tabs: some tabs could not be loaded.
Please try again by refreshing the page.
If you are still encountering this problem, please check your server logs or contact your hosting provider for assistance."

 

I've tried deleting all categories and adding new ones but still get the error.

 

Any advice on what is wrong?

 

TIA!

Update: there is also no category shown in BO " parent category"  where you collapse / expand category tree. also no category tree to choose from when adding a new category.
