Unable to edit Content Editor Webpart – Error on page

Issue
While moving the Content Editor Webpart from one place to another We get the following error message “Error On page” on the Bottom left of the IE.
Or
After moving the content Editor Webpart, when we click Exit edit mode. It gives “Unexpected error has occurred”
Cause
This usually happens whenever we copy the HTML code from one Content Editor webpart to another, due to which the Webpart ID is also copied and it conflicts.
Resolution
Modify the Content Editor Web part
Open the Source Code
Remove the following Tag from the code for e.g.:- ”id=WebPartWPXX WebPartID=”XXXX-XXXX-XXXX-XXXX-XXXXXXXX“
Let me know in case of any doubts.
