conflicts with photo gallery by webdorado

I’ve been using photo gallery for over a year now, but I’ve just discovered that I cannot save a new gallery. Each time I try to save it, or apply changes, I get an error about how the action was blocked from Wordfence’s firewall. The whitelist button is there, but this is the only plugin that it won’t let me click any buttons. It’s like it’s stuck. It does give me a partial URL though in the message, so I tried to manually whitelist it in the wordfence firewall settings to no avail.

Also, pages that already have embedded galleries are no longer displaying correctly.

Any tips on a workaround for this issue? How can I resolve this?
