Hi Danish,
My fan page URL is https://www.facebook.com/roadtrip.to.16
When your fan page URL is inserted into the plugin, the like box appears. While when I insert my fan page URL into the plugin, the like box does not display.
I thought it was probably an issue with the restrictions, but there is no option on the fb page to choose country/age restrictions. I changed all of the settings to public, and it still doesn’t work.
Thanks for taking a look.
Best,
Jackie
