Hi, Developers! At registration of the user, the forum has produced an error: E_USER_ERROR - Unable to send e-mail! The hosting. Sendmail works correctly, from a site go, but from a forum is not present.
I have found solution of this problem. In a file functions.php on string 1198 in function mail () I have deleted a code '-f '. $ from_email but php5 for me works not in safe_mode! Obviously, it is a defect in usebb as other scripts correctly send email.
