erm, I had this exact same problem a couple months ago, and have attempted to install sourcebans again (I never figured it our previously.) But for some reason, everything on the website side of things is fine... I can kick and ban through the site, and unban.. although I have set myself as admin on my server, and the server detects that an admin is online.. yet when I try to use sm_ commands.. it says I don't have access to this command?
edit: this is sort of weird.. It's like the server isn't reading the admin groups properly. Console is giving 'Loading Admin Groups...' message, but isn't giving a confirmation message to say it has loaded it (as I'm pretty sure it is meant to do?)
It surely must be connecting to the database ok, because if I deliberately mistype the username for the database user, console says it access is denied for the user. Is there possibly any way I can specify the admins manually through the .lua file or something.
