Conflict with WordPress Security plugin

I don’t know if the project is completely abandoned, or not, but I posted a few years ago about it not letting me connect to a gallery, and I’ve found others online searching for a solution to the same problem.

I don’t have the solution yet, but I have narrowed the problem — the other security plugins, including WP All in One, have firewall rules that seem to be blocking the popup. Surprised the developer didn’t mention that as a likely cause many months ago, as it may lead to a relatively simple fix (add an exception to the firewall to let that connection happen).

We’ll see how it goes, and I’ll post an update.
