Yea.. I spent a good chunk of the day yesterday trying to figure out what had happened to all of the FPP cape uploads. They are pretty much all broken in 2020.05. 2020.06 (released this morning) contains the first part of a fix. It will require you to reselect the Vendor/Model and now the "Variant", but I believe the upload should then work correctly. That said, ALL of the controller information changed from 2020.04 to 2020.05 so there definitely could be additional bugs as the information was moved from all the various placed in xLights into an XML file. Finding/reporting any bugs found would be a big help.
