Debug mode: off

-bash-4.2$

Unfortunately there are some issues:

1. Fof-upload extension: no response when clicking on uploaded image (expected behaviour is image download)
2. Admin-area: categories; some of the categories cannot be opened for editing (?)
   It might have something to do with hidden categories (not visible to all users).

Do you have suggestions?
Thanks and best regards,
Erik

askvortsov Yes there is, for example in the error-log:

Solved by removing the Dutch language pack!

Many thanks askvortsov !!

Only remaining problem is the problem with the 'tags' (admin area). Some of the tags cannot be opened for editing (?)
It might have something to do with hidden categories (not visible to all users).
