I’ve emailed WordFence about this and they’ve confirmed a new fix is on the way for the problem with saving Firewall options.
Took me a while to realise but you can check what is causing the false positive by going to the Live Traffic menu option on the WordFence menu and selecting the “Blocked by Firewall” option from the drop-down. You can then at least try and put in place a work around on the page if you are desperate to update it.
I am also having this problem and it’s causing problems when updating Posts. Did anyone come up with a fix for this?
Any help much appreciated.
