I can comment on posts fine, and I can highlight on pages fine, but when I highlight body text on a page and hit the comment button, the pop-up asks "go to this post?" and selecting "continue" does nothing. I have mainly purchased this plugin to allow users to comment on the body text of pages, not posts.
The plugin works well with pages just like it does with posts. It's possible either the plugin settings are not correct, or there is some sort of conflict with the theme or another plugin. Can you try briefly activating the default WordPress theme and testing to see if it works on pages and let me know? Thanks.
