Due to some hacking attacks on our web forums our Hosting Provider moved our forums on temporary server. After we stopped the attacks the forums were moved back into production server by our hosting provider. But it seems that some settings were lost. Thus there were some issues like it was not possible to create new users for the forums.
Today we manually corrected all the settings. The forums should work fine from today.
