I'm sure you can find an existing script to detect adblockers and display messages in place of ads.
I haven't looked extensively into it, but this site should have something similar to what you need.
What could be causing this issue?
Send me a message if you want to see the theme in question that I'm having this issue with and I'll send you a link.
Not sure if my lack of container-fluid or lights-out button in the bottom right of my site would have anything to do with this, or @Ted having more or less the same issue. I recall him mentioning @julian was looking into it. But don't think he was fruitful in his search.
I was not, no... @Ted's server wouldn't start up at all, except in dev mode
i removed pidfile and it started normally
