ColdFusion Administrator 2018 error - error invoking CFC
I am working on an install of CF 2018, and have migrated a website that was working in CF 8 (yes, I know, it's ancient) and is not working now.
In trying to match the settings between the two installs, I apparently moved or changed something that has now caused the CF administrator to stop working. I can't get IN to the CF administrator, so I can't find the setting to fix it.
On the Administrator index page, instead of getting the login page, the page is black with a search window on it. There is a popup that says "Message from webpage Error invoking CFC /CFIDE/administrator/updates/download.cfc : WDDX packed parst error at line 1, column 1. Content is not allowe in prolog.. [Enable debugging by adding 'cfdebug' to your URL parameters to see more information]
Adding cfdebug isn't giving me any other information.
How do I fix this without uninstalling and reinstalling the whole program?
Thank you
