Not long ago I was getting this message every time I tried to go anywhere on this site, it's fixed now:
Warning: mysql_connect() [function.mysql-connect]: Too many connections
Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later.
Yeah, that happened to me like 8 times today, something about something being modified.... But it works now LOL...
An update to the server most likely caused the database to be unavailable for a period of time off and on. If you experience any other issues, please let me know.
