WordPress database error: [MySQL server has gone away]
I did not make any changes, and the host says that there is no problem with MySQL. Can anyone explain what the error means? and how to troubleshoot?
This is a shared hosting environment, and no recent changes where made to the site. Also other wordpress sites are encountering the issue with this same shared server.
This is not a WordPress error, it is from MySQL:
Talk with your host again.
Talk to your host and consider finding a new host; it’s not that difficult to run a MySQL server.
