Apps not showing in my website

I have installed three apps in my website but none of them is working. What i tried:

Installed uninstalled apps
Went on Developers mode
Turned off Rocket accelerator
Surfed my website on private mode
Cleared cache and force loaded website
Tried all possible browsers

These are all the steps i read in the forum. If you have other suggestions i would be glad to hear them.

Apps installed are Addthis, Addtoany and Facebook comments.

Please help.
