I believe the Plugin Firewall Additional Whitelist Tool I mentioned above would allow you to keep the user as an Author. You would just need to select the Author checkbox. 
I believe that option is an independent option, but you might as well do all of the Plugin Firewall setups steps again for good measure if you choose to go that route. Personally I would not choose to do that since the only User Role that I would want to have any access to the WordPress backend features/functions that could be used maliciously against a website would be an Admin ONLY and no other User Roles.
