Additional WordPress 5.8 widget not working

When trying to edit widgets that used the “Custom HTML” widget box, I’m getting the “Potentially unsafe Operation” warning, but it won’t let me click the check box to continue anyways. There was no problem before the new WordPress 5.8 Widget “Block Editor” function. Somehow this function is conflicting with the WordFence’s detection.

From the Wordfence Dashboard click on “Manage WAF”. Then you will see “Basic Firewall Options > Web Application Firewall Status”. Change the option to “Learning Mode”. Now perform the actions such as page loads or edits that were causing issues. This will help Wordfence learn that these actions are normal and it will allow them in the future. After you have finished performing the actions, switch the WAF from Learning Mode back to “Enabled and Protecting”. Now after these actions, it will work correctly and properly.
