Hi Brijesh,
Firstly, I noticed that your Joomla version is quite old(3.3.6). Actually Joomla has addressed many security issues since older versions, which is why I'm wondering whether you have any plans to upgrade Joomla to the latest?
It will also allow you to update many plugins and extensions to the latest version so that you do not have compatibility issues.
For the post edit button, it looks like there is jquery conflict which I then helped you enable this setting(
http://take.ms/52LcQ). Post edit should work fine now.
Not really sure what you mean by 'social media post not working', but if you are referring to FB share button(
http://take.ms/nJd3q), it looks like there is conflict with the plugin
sh404SEF core - Social buttons(
http://take.ms/QRwR9). If you are currently not using the plugin, you may disable it.
