Hello Ron!
Thanks for the answer,
yes indeed, its the server.
I had to disable and enable again mod_rewrite and then it worked.
The support told me it doesnt take new mappings, although the previous are working.
Thats why i had to switch mod_rewrite off and on again to get the new mapping.
So for all people who get that error:
Try the mod_rewrite first…
have a nice day
