Thread:Project:Support desk/Cannot contact the database server: Access denied for user/reply (7)

While I - just like Florian - see the error message about Semantic Forms, this is not the initial issue.

The error "Access denied for user 'username'@'hostname'" is caused be incorrect credentials. For example I see that you are using two different MySQL usernames: You used "newqmrasite" in your first post, but now you use "wikiuser". Again, please make sure that you are using the correct username!

@ Florian: Is it intended that in your script you are not defining $wgDBname (while you are later using it)?
