After Edit Unit Planner getting Error

Dear Support Team,

After updating the Unit Planner, when I try to go back, I get an error on the page and am unable to return. attach here console error.

Hi @vishalr This looks like a JavaScript error related to the TinyMCE library, and I haven’t been able to reproduce it in testing. I notice from the error log, the URL still says v=28.0.01. Can you check to see that your database is updated via System Admin > Update, and perhaps also clear Front End Cache using System Admin > Cache Manager, to help force a cache refresh.
