Please check the server logs(error.log) under quickstart folder and see if there are any issues in the logs

Thank you Krati.

Hi Krati, Thank you for the reply, Basically business wanted the ability to reference a variation of the fragment to be able to define and select the slight different content fragments.   They also want to display the title of the referenced content fragment just above the path field. Please suggest...

Hi All, Currently we are not able to add a fragment reference to a variation of Another ContentFragment in the reference path browser in the ContentFragment model. We are using AEM as cloud. Has anybody tried this or anybody has done any customisation to same?
