Got everything working fine on my //localhost/ testing but when I uploaded my page to our source control and other developers downloaded it, they're getting the above Javascript error. Also getting same error on our Staging site. On the Staging site, I realized that the web.config wasn't updated to reflect the new stuff I had to add to our //localhost web.config. So that could be causing the error there. But other developers have the web.config updates when they downloaded the updates from source control and still not working.
I can see the call to CuteWebUI_AjaxUploader_Initialize in the page source. It's in the code generated by this line in my .ascx file:
<CuteWebUI:Uploader runat="server" ID="Uploader1" InsertButtonID="UploadImage"
CancelButtonID="CancelUpload" CancelAllMsg=""
tempdirectory="~/UploaderTemp"
onUploadCompleted="Uploader1_UploadCompleted"
onfileuploaded="Uploader1_FileUploaded" >
<ValidateOption AllowedFileExtensions="jpeg,jpg,gif,png" MaxSizeKB="1024" />
</CuteWebUI:Uploader>
Thanks for any help and advice.
