This is a notice email to let you know that SMF could not connect to the database, contact your host if this continues."
Some of my members can not connect But other days they can. I need some help please!
I kinda like this attitude. Though you will have to live with the occasional email about database connection problems as we periodically restart mysqld and in case anyone is accessing the forum that very moment a database error message will be displayed and you will receive an email letting you know that there was a problem with the database.
You should keep in mind that with free shared hosting there always will be some limitations and/or issues. To avoid such problems you are welcome to upgrade your account to premium and be hosted on servers with more resources.
