Ok guys , I tried to upload my page in two other hosting services , blue host and hostgator.
One of this was of my friend.
Firstly I uploaded the site at bluehost and asked some of my friends to visit the page. Just 3-4 visitors, and the CPU of the server went to 80-90 %. for about 1 or 2 hours the hosting service has suspended the account.
I uploaded to hostgator and the same thing happened but this time without a single visitor. I deleted all the files becouse with no doubt they would have suspended even it.
I don't know where the problem is , I have about 200 registered members in my wordpress site , about 200 posts and 70 comments.
I have tried to not overload my wordpress site. It has only the theme and 5-6 plugins now.
I really dont know what to do.
PS: Sorry for my english, I am not from US or UK.
