For some reason my website started being slow...Then i asked some developers thinking it is their plugins but the said it could be a server issue i must ask my hosting company.
--- DEVELOPER'S SUPPORT RESPONSE ---
It all looks like a server issue.
1) Check with your host if they migrated their server.
2) Check if your host has changed any settings or maximum processes..
The hosting company responded by saying its a database issue :
its definitely NOT a server issue. In your case it is a database problem. The database got stuck (see screenshot)
A good web-developer is easily able to handle that.
Anybody have any idea or could advice on how to fix this ?
