We are using Telerik Rad-editor (Version: 2017.2.503.40) in our application. The Rad-editor control which we use looks like the sample you provided in "Save in database" link.
We are facing 1 issue while uploading image through Image Manager control. If we upload an image then we face 1 console error. Below is the description for the error.
ScriptResource.axd?d=WumqVucm-BTOpradDSIl6FwWq2Nf8yJ7sqq9-igzn7fhpcm7LMUuXAF__xzJt_PP7G8atwaBX_21lH9wtho_Q-JsnyL97IPmZiErbgIsKQvtmeYlHiL_GqtD3HsMVT9KS6u1-fBfjgRuY07t3m9OjNcjVdzCqYRpX7UHxymyD6WPAuy90&t=ffffffffad4b7194:5 Uncaught Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
Can you please provide us the solution/your suggestions please?
Thanks in advance.
