I'm trying to add variant of persona in Kentico 13 for that I have created an personalization condition type for getting all personas. In personalization All the Personas are coming but after selecting persona when I click on add variant button then an editable area comes inside it and gives an below error.
An error has occurred. If the problem persists, contact your system administrator.
I have tried to find out it in event log but there is nothing in event log related to this
