With AjaxControlToolkit 15.1 found a problem with HtmlEditorExtender.
If I insert one or more images in the text, the upload stops on 100% upload on the first image with this error " run-time error of JavaScript: Sys.ArgumentException: Impossible to deserialize an empty string"
Attached are the error message and the upload image box.
Comments: You should add AjaxFileUploadHandler to your Web.config file to make it work: ``` <configuration> <system.webServer> <handlers> <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit" /> </handlers> </system.webServer> </configuration> ```
