If I try in to revoke for example DELETE rights in Profiles (lets say SALES PROFILE), it will not save the changes. Even worse, vTiger will GRANT all DELETE rights for all modules, even if they were not granted before.
Worst case is the guest profile. If I EDIT it and just change one right and SAVE afterwards ALL RIGHTS are granted..... :-((

What to do ?

I want to revoke delete rights from lats say normal users....

Thanks for help
