"Share post"... what do you mean?

"Chat"... what plugin?

If you want any useful advice, then you need to post at least some more information. If you want information / guidance to any 3rd party plugin you have installed and that don't work, it's best to ask on the corresponding plugin page first.

chat: facebook like chat, i delete create by ***** end dont work,

share post is the one where you write what you think

chat: still don't know what plugin you mean. There are several chat plugins available. Why don't you simply describe your problem - in detail - on the corresponding plugin page? If you say you deleted something... did the plugin work before? Maybe you simply introduced a bug when modifying the code...

"share post": sorry but "where you write what you think" does not help me in the slightest to guess what plugin you are referring to. Does the plugin has a name? Is it a bundled plugin or 3rd party plugin (link?). Again, more details are needed to give you any proper advice. If it's a third party plugin it's best to decribe your problem on the plugin page. The plugin developer could help you best.
