I have this error while trying to "Read Mail" in usermin: Undefined subroutine &mailbox::open_dbm_db called at ./mailbox-lib.pl line 1447.
I am using Usermin v1.450 on CentOS 5.4, webmin is v1.520.
/var/log/miniserv.error shows a similar message: "[11/Sep/2010:22:09:01 +0800] [188.8.131.52] /mailbox/ : Perl execution failed : Undefined subroutine &mailbox::open_dbm_db called at ./mailbox-lib.pl line 1447."
I can only find one posting related to this on the forum, but it was unclear what was the solution.
The permission on the mailbox-lib.pl and folder-lib.pl (and the rest of the files) are owner: root group: bin permission: 755 / rwxr-xr-x
Any help/advice/troubleshooting tips will be greatly appreciated..
thank you very much :)
