We have a discussion going here about this being off topic. Others are saying it may fit in another site better. I'm trying to figure out if this would be on topic for Stack Overflow, and if not, are there any relevant meta posts explaining why?
Serverfault may be better. Stackoverflow focuses on programming questions. While we typically allow that to leak to developer things, PHPMyAdmin isn't developer specific.
To expand on what I mean by leaking, I mean things that developers use but would be categorized elsewhere if it weren't a developer product.
For instance configuring a browser add-in would be super user, however configuring Resharper a Visual Studio add-in, may be allowed.
Since PHPMyAdmin isn't a developer product, it doesn't fall under that exception clause. Keep in mind that PHPMyAdmin is a tool developers use, but not a developer product.
