The plugin is messed up

The shortcodes for like and send button are not working. When i put the code somewhere in single post php code, it shows like simple text and i didn’t put it in <p>.
Publish to friends timeline, sometimes working, sometimes not.

Sometimes, wordpress admin panel it’s giving php errors and it’s very very slow. When i click add new article, for example, i need to wait like 5-10 minutes to get the page loaded. If i disable the plugin, everything it’s ok. I try disabling all other plugins to see if facebook plugin get in conflict with another plugin, but it was the same thing, 10 min to get a page loaded, when this plugin it’s active.

My publish action was not even acceptep beacause they say that i have to many videos on my blog. WTF?! I have a category for catoons. And i publish episodes.
