Mediathek addons failed with error "Invalid param"

Hi.

Most of the german mediathek addons failed with "invalid params".

I'm not able to find more in the logs (http://ix.io/4EQ3).

Does anyone have any idea to deal with?

Thanks in advance.

Best to read/check the add-on support thread in the Kodi forums.
