Hey please try to understand...before this Database Error on my site comes, in my site have around 100 post.
This all has done after Establishing Database error Comes...i am really frustrated and not happy with this answer.
There is no post in this site kindly please get my database back from your last old back.
Please help out and i am really worried and not happy with this kind of service.
This iis 3rd time i am facing this issue but this time whole website data is erased.
You've never said about your site being erased in the first place, if you're getting errors then that's nothing to do with missing files (excluding SQL files, maybe).
As Dead-i said, when he've went on your site, there was no issues what so ever for him.
Anyway, I'm also getting MySQL issues (database keeps on disconnecting at random times), I've kind of fixed it by removing some stress (refreshing after 4 seconds) from my chat which did help (it was the counter mainly), my chat does though go blank at times which from the looks of it meaning that connection from the database was lost from so much input.
That above is my issue with MySQL, for you, I don't know if it's similar to that or you simply don't have the tables/database in place for some reason.
