I have a server running in 3307 port mysql, everything was doing fine, but suddenly I cannot connect to the server, not even locally. When I try to connect locally in the 3306 port, I can and I do see my databases, but they don't have any data inside, in fact they don't have any tables. So I checked the data folder and there are my .frm to every single table I used to have. Do you guys have an idea about it? Or tell me, is it possible to recover all the information just having these .frm files?
(Also, I reviewed the config file and yes, the port is 3307, but why I can't connect through it?)
