Pay with a like JS error: Uncaught TypeError

Hi guys

I'm trying to get this plugin to work and I'm currently having two issues. Maybe solving one with fix the other..?

If I 'unlike' the page in question anmd clear my cookies so that the page with hidden content (https://germaine-de-capuccini.co.uk/win-skincare/) is ready for me as a new user, the 'like' part works and the confirmation pops up (although cut off due to the inline style height:20px imposed by the js). However, the content isn't revealed and I get the following js error:

Uncaught TypeError: Cannot read property 'errorText' of undefinedjQuery.ajax.success @ pay-with-a-like.js?ver=2.0.1.2:281m.Callbacks.j @ jquery.js?ver=1.11.2:2m.Callbacks.k.fireWith @ jquery.js?ver=1.11.2:2x @ jquery.js?ver=1.11.2:4m.ajaxTransport.send.b @ jquery.js?ver=1.11.2:4

Any ideas?

The other issue is that if I already 'like' the page when I arrive I am still unable to see the content whether or not I click the like button.. I guess this would be resolved should the first issue be fixed.

Thanks in advance for your help!
