Category Error: accessToken invalid

Hello,

I got the error on the category section:

: 'accessToken' invalid: can't be null

after set the top categories my try to set the first category down the line, after saving the main category was deleted and could not found. Also the categorie ID was eliminated. After that problem the error "access Token invalid" appears.

What is to do?

Regards
George
