Why do I get a max_user_connections error?

The max number of simultaneous connections to your MySQL database is 25. This normally is not a problem because MySQL connections are made and destroyed within a fraction of a second. If you are getting a max_user_connections error, it could be:

  • Your code is opening the connection to the database, but not closing it. Please see the following link for more help with properly opening and closing your database connections: https://www.w3schools.com/php/php_mysql_connect.asp
  • Your software is configured to use pconnect / Persistent Connections. Please read the script/software documentation or contact the script maker of your software to find out how to disable pconnect.

For the most part the problem is due to pconnect.
