Was working fine until this error started appearing!

I loved everything in the plugin, and thought it to be the final thing for sharing plugin for my site. But then a new problem surfaced: While sharing some new posts, no description or title of the post shows up. instead var hupsp_t smthng codes are showing up. I just don’t know what caused these errors like this out of nowhere. But I do remember I had updated the plugin as soon as they were made available, but hope that didn’t cause the problem as only the latest posts are showing up this error.

Can anyone please please help me out?? I can not share my posts on facebook page anymore bcoz of this. Please help!
