Hi, Unfortunately I removed owner group and desiner group for shared document, So just visitors have access to shared library. know I want to corect it and give permission to owner and designer (not visitors) the problem is that I have access to shared library with setting feture, I gave full permission to visitores but it does'nt work, I tried admin account but it dosen't work I tried to access to that library through other parts, No success I'm realy stock on this first step. how can I delet or change that library know? Thanks
