Error: User has exceeded the 'max_queries_per_hour' resource

Sometimes I am getting an error notification: User has exceeded the 'max_queries_per_hour' resource (current value: 15000)

I am using a PHP and MySQL database.

How can I fix this ?

Hi,

The error notification User has exceeded the 'max_queries_per_hour' resource, means that number of executed SQL queries is limited on the server. The limit can be changed or removed.

You can get this error often if you use some free hosting services. In that case, the limitation probably can't be changed or removed from user side.
