Website not opening except home page

Site URL?

Can you login to your dashboard?

Yes I can login and do everything in my dashboard even I can view all my posts, pages, can edit them and can publish them as well. But can’t view those pages. ??

Try these:

1- Reset permalinks to default and see if it helps
2- Deactivate all plugins and see if it helps
3- If the above steps do not help, revert to Twenty Eleven keeping the plugins off and see if it helps.

Thanks for reply. It worked. I changed the permalink and it worked. thanks a lot.

Glad to know that you could fix the problem.
