I bought this plugin 36 hours ago and after following all the instructions, the Share button worked immediately but I was getting an error on the front-end when hitting the Like button. After contacting khawaib, he informed me that at the same time I was buying his plugin, he was uploading a Newer version to his site. So he gave me the newer version (and since I'm not a techy he went into the back end and installed it for me). It works great, looks fancy, and i LOVE this plugin. Great addition to my site.
