This plugin is not working very well for me. The ID's are not being added.
I initially had it network activated, then thought maybe it would work better as a single activation (not that I could think of any reason why it would work better that way), then I thought maybe my social sharing plugin was causing problems, so I deactivated that, but none of these things seem to help make the plugin work.
Any ideas on what might be causing this?
Here's a page with headings which I assumed would get ID's on, but sadly they are not :/
