I clicked all the right buttons many times before and couldn’t get it to work, but this time when I enabled it on pages and pointed to the post settings, it started working just fine!!! Maybe there was a conflict with jetpack’s “like” widget? I had disabled jetpack and it hadn’t seemed to make a difference. Maybe it took more than refreshing my browser: maybe whe I eventually logged off and then logged on later it refreshed the browser’s memory? I don’t know what the issue was, but now it’s all working. Thank-you for confirming that LikeBtn works on Graphene, otherwise I was giving up on trying and wouldn’t have known that it can work! LikeBtn is awesome!
