Error create a Widget in Kentico 12 MVC

mark json asked on March 8, 2022 07:27

I got an error while creating a widget. I followed documentation from here

License for feature 'ABTesting' not found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.


  • Initializing the page builder in the controller
  • Adding editable areas to views
  • Loading page builder scripts and styles
  • Developing widgets in MVC (develop NumberWidget sample)

I using a free license key for my localhost. I removed builder.UseABTesting() method in App_start/ApplicationConfig.cs but error is unresolved.

Can someone help me? Thanks in advance!

I would also recommend turning off the online marketing features in Settings -> Online marketing. Then, what version are you using? What hotfix is applied? There were some licensing bugs fixed too.
