wp-options keep crashing please help
My wp-options keeps crashing and am getting "error establishing a database connecting" when I try loading the page. I don't know whats causing this to happen, I read somewhere that I might need more ram so i upgraded my plan to get 2GB of ram 40GB of space. But today it crashed again, I repaired it and went to the error logs and this the same error i get when the wp-option crashes
