Thank you so much for replying.
From your reply, i understood that in our SharePoint server we had used 2010 version of Telerik suite and now it is unsupported in our new server, since our system is built on SharePoint 2010 and later migrated to 2016 version.
So to solve that, your are suggesting us to to install the latest 2013 version of telerik suite in the new server to run the features. is this correct ?
Please help to understand you solution in a better way, so that i can use that to fix my issue.
And to answer you next question, we are unable to find out why this telerik.web.ui is broken.
