What should I do?
Firstly, please contact our Support Team as soon as a malfunctioning script is available and overuse to open connections to the database servers.
Moreover, make sure you provide the database server with a username and password, otherwise you will connect as Apache@localhost and will do not work.
In addition, using persistent connections will lead to over-use of funds and connection error. This feature is only suitable if you have a server of your own.
