Hi Friends,

 I have upgraded DNN version to 6.1.4 from 5.6.7 the host settings page stopped working.

Note: The upgrade had not any error. It was showing success for all tasks.

Please help. I have mentioned error below.

Hi John,

Thank you for the response.

I have checked the link http://www.dotnetnuke.com/Resources/Forums/forumid/-1/postid/328438/scope/posts.aspx but I do not see any duplicate records in the table ModuleDefinitions.

The above thread was created about 2.5 years ago and I believe there are lots of updates done in DNN 6.X version afterwards.

The host settings was working well with 5.6.7 version. It is creating issue for 6.x onwards.

Must appreciate for any suggestion.

Regards
Ketan

Thanks Bill for the prompt response.

I do not see any duplicate controlkey for "CONTROLPANEL:RIBBONBAR" in the ModuleControls table.

Ketan.
