Been running ispconfig on Centos 5.1 flawlessly for months now. However, today I had to reboot the server, and when it came back up, i noticed I could not log into the isp control panel at http://myserver:81. All login attempts were countered with the dreaded error 101! System users cannot access the web control panel either. Now, all services appear to be running normally. All web sites are still up and running. Email, FTP, and DNS are still functioning properly as far as I can tell. I have read thru a few posts regarding generic error 101s, and i can assure you that the database looks fine. I even tried changing my admin password via the mysqli cli. (i noticed that the hash didn't change when I ran the command, so i am remembering my old password correctly.....) I am nervous to do anything to risky now since my clients are still up - but wat do you all think I should try next??????????
