Hi Mark,

We are not aware of this error and will need your help to reproduce it.

Do you get this error in a specific browser or in all browsers?
Are you able to reproduce the problem in the live demos of RadEditor?
Does the problem happen if setting the StripFormattingOptions property of RadEditor to NoneSupressCleanMessage?
Can you also disable the AJAX to see the real error message - see Get more descriptive errors by disabling AJAX.

Thank you!

Best regards,

It was in all browsers. The live demo works fine.No Ajax being used on the page.

 

I set to StripFormattingOptions="NoneSupressCleanMessage". Now it is working. Any idea why that simple change makes a difference?

Hello Mark,

When the StripFormattingOptions is set to "NoneSupressCleanMessage", RadEditor does not take any action of stripping the formatting of the pasted content from the clipboard. You can find more information at RadEditor and the Browser Clipboard.

It looks like the pasted content contain something that breaks the cleanUp functionality in your version of RadEditor. If this is an important feature for you, my advice is to migrate to the latest R1 2018 version (2019.3.910) and test it.

If the problem still persists, please open a support ticket and provide steps along with content to replicate the issue on our end. Thank you!
