Why my sites going offline - is there any script problem?

Hi,
I manage some sites and most of them are article directories.
article directories are based on Articlems, Articledashboard and Articlesss wordpress script.
At first I was with shared hosting but my sites were offline and moved for VPS and already tried big names such as Myhosting and Mochahost but there was same problem with my sites and they went offline again and again, so I don't think it is a hosting problem, it may be any script problem.
Guys I'm unable to decide what the problem is? as I'm unfamiliar with programming.
if there is any script problem, what script is causing this error and please help me to know what should I do to fix this problem?
I'm really frustrated my sites is going offline and I'm loosing my money.

Thanks in advance.

 

cek your server status..and look at the problems details..

 

how many scripts do you have bro .....

 

I'm using 3-4 scripts.. such as Articlems, Articledashboard and Articlesss wordpress script and SMF etc.. in just 10 sites.

 

Google ses dont like to many scripts in a site - be aware of that notion ... make sure youre adding fresh contents on that form - and many more new clients ... best wishes

 

Did you consider a conflict between the scripts? Like working together but consuming to much cpu to do that?
