It doesn't work

I had a free ‘like’ button that stopped working so I decided to install this because you usually get a better product if you pay for it. Not in this case.

I couldn’t even set it up. It was requesting an API key but after following the instruction on the App website there was no API key there.

I went to the App provider’s forums but it won’t allow my to login. Pressing the login button refreshes the page but doesn’t log me in.

Time to give up but if anyone knows of a ‘like’ button plugin that does work I’d love to know about it.
