Problems creating new main categories

[dayakoulileikes]

Hello

 

I have a problem with my Installation of OSC2.2.

 

I cannot create new main categories or edit or delete existing ones.

 

Creating and modifying subcategories works fine, just the main categories simply do not react to any attempts to alter them or add a new one.

 

Does anyone have an Idea what might cause this Problem?

 

Thanks for your input
