Hi,

I am getting an error with the telerik image manager (when editing content) after upgrading to 5.6.3. (after upgrading from 5.6.1)

Anyone else having problems after the upgrade.

Worth taking a quick look at this blog to see if it resolves your issue: "

Before upgrading to 5.6.3 read this

Thanks for the link.

My issue appears to be different:   I have the correct reference to the Telerik.Web.UI.dll in my web.config - and the correct version of the dll in my bin folder.  The only problem with the Telerik HTML provider is when the Image Manager icon on the toolbar is clicked.  That is when the error in my initial post is logged....

One of the security changes in 5.6.3 was to modify in web.config the <pages . . . /> element to set the enableEventValidation attribute to "true" rather than "false" as it has been prior to 5.6.3.

Just a hunch . . . but try changing enableEventValidation back to "false" and see if the error goes away. If it does, make sure that the DotNetNuke.HtmlEditor.TelerikEditorProvider.dll file found in the installation's \bin folder is file version 5.6.3.0 and that all .ascx, etc. files found in \Providers\HtmlEditorProviders\Telerik were also updated to the latest versions. If the assembly is an earlier version or the the .ascx files for the TelerikEditorProvider did not get updated it would appear that the installation of the TelerikEditorProvider_05.06.03_Install.zip package contained in the \Install\Provider folder of the 5.6.3 upgrade package failed. If that is the case I would try re-installing the TelerikEditorProvider_05.06.03_Install.zip package using the Host-->Extensions, Install Extension Wizard.

Don't forget to reset enableEventValidation to "true" following resolution of this issue.

In any case, I'll be interested to know if my hunch is correct or I'm way off base . . .

Hi William,

Thanks for the reply - very much appreciated - I checked all that out - and everything checked out OK.

Just to re-iterate - the Telerik HTML Editor seems to be working - with the exception of the Image Manager icon on the toolbar.  Very strange...

For now, I've reverted to FCK - but would really like to figure this out...
