How to resolve this? I tried to do the version control. but still facing the error. I was downloading the barcode scanner from marketplace. It was showing the previous error. Though it is showing But while adding widgets, The barcode scanner is not showing in the widget panel.
This errormessage gets shown when StudioPro tries to import the widget-files in /widgets. Every single file in that directory should be a widget-file, but apparently one of them is not. Click on ‘show details’ to find out which file is causing the problem and remove it from the /widgets directory
