Pay with Like not working well?

Im getting quite a lot of emails from unhappy website visitors that say e.g.

"I tweeted the Northern Lights Iceland page but I was still not able to see the forecast. Can you look into this? Thanks!"

This is for http://www.northernlightsiceland.com/ and they click on Northern Lights Forecast in Menu and are supposed to get access to the northern lights forecast. I have been getting this problems questions number of times. Im doing something wrong?
