I have installed roster and all seems fine. When I upload the profile the Guild Master (me) toon is level 0. This toon is a 60. What could be the issue?

I see this occasionally. I have no idea what the cause it. But for us, it is not the GuildMaster @ level 0. It is the person uploading the the roster update.

Had this problem with one of my guildies. I had him login to Wow, save his profile, and reupload it, and it seemed to fix it.

I have also found that sigs don't always update themselves correctly on the character display page, but a forced refresh (ctrl+f5) makes them update correctly.

If the problem is indeed solved by resaving the profiles, it's probably a cp issue.

If the sigs don't update it's probably your browser caching them. There are ways to keep browsers from doing that, but honestly, you don't want that. Especially if you use your avatars on boards like this one.
