I keep getting this message...
Warning: mysql_connect(): Too many connections in /home/user/public_html/4images/includes/db_mysql.php on line 39
This is a MySQL server configuration/load problem that only your hosting provider can resolve. Contact them for assistance.
A quick fix is to restart the MySQL server which clears the overload of connections but does not prevent it from happening again. Analysis of load and configuration settings is needed to devise a permanent solution.
