Fix MySQL errors

I'm using Joovili script. I'm having the following MySQL errors: Warning: mysql_connect() [function.mysql-connect]: User user444_user has already more than 'max_user_connections' active connections in /home/user444/public_html/include/[login to view URL] on line 23 User user444_user has already more than 'max_user_connections' active connections I contacted my hosting provider regarding the error above and this is what he said: "There are limits to the amount of connections a single user can make to MySQL and you are exceeding this because you are using a single user for all databases. You must create and assign a separate user for each database to prevent this from occurring." Today, I also got a new error. The error is: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/user444/public_html/themes/default/[login to view URL] on line 17 Table './user444_db/joovili_guestonline' is marked as crashed and should be repaired
