Matt Knowles ,,
thank u for ur time ,,
but actually , I have used the same theme with another wordpress website , and everything was working normally , with no load …
I have checked the average CPU usage for the whole server which has more than 20 websites , and the average was about 2% – 3% , even with activating the other wordpress website which has the same theme and even has more plug-ins than the one Im asking about ,,
so , I dont thing the problem is with the theme itself nor the plugins ,,
it might be with the database or some activities by users that cause the load ,,
