RMS Payment Gateway iframe blocked by WF setting

Thought this was worth raising here, and with https://www.retailmerchantservices.co.uk/.

We use RMS to handle payments on one of our websites.

We noticed that logged in users (admin) who were using the gateway, were unable to load the RMS iframe which handles card details.

After speaking with RMS, we were still unable to resolve the issue.

Eventually, after testing plugins, we isolated it to WF, and then isolated the issue to a particular setting.

The setting which was blocking the iframe from loading was under ‘Whitelisted URLs’ > ‘Monitor background requests from an administrator’s web browser for false positives’ > then deselecting/unticking the ‘Front-end Website’option.
