I never got a chance to even suspend the site myself. * By server admins did that for me, and then suspened that domain which was causing problem. I installed CloudLinux, and then unsuspended the site, deleted all plugins and the site was working fine. * Now one thing I can rest assured is that other sites won’t be affected due to one site’s issue. I tried all methods but most are not practical to do if you manage lot of clients who use WordPress. * For now am just going to use limited plugins until someone finds a proper solution. I hope such things do not happen with WordPress 3.2, whenever it releases.
