First of all,if you could please click on the archive link and tell me what crap this code is: http://www.successstories.co.in/archives-2/
Secondly, some categories aren't opening; they are getting redirected to other categories.
Third issue is the load time. I have checked with my host provider and they said that the problem was with the theme and not with the server.
The blog gets about 3000 visitors a day and it is so embarrassing for us to not fix the error.
Note: I deactivated all the plugins to see if any of them were causing the problem but the real culprit seems to be something else.
I will appreciate your questions,
