Hi,

I used stsadmin to retract and uninstall the .wsps for List Forms Extesion.
After that, whenever we create a new web app, follow by new site collection, blank site. When we create a new document library there, we get this error.

Futher investigation showed if I add the following entries to the web.config of the new web app, we will not get this error.

So, my question is how do I completely uninstall List Forms Extension and remove all the references to it and its dependencies.

Could you please assist? Thanks heaps. Our SharePoint is 20010 SP1, Jun CU

Cheers

Hi,

Could you please check that all SLFE files (___SLFEDefaultTemplates) were removed from C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES folder in each WFE server.

Sorry, forgot to paste the web.config entries:

Hi Igor,

Thanks for replying. I have received the same suggestion from the KwizCom Support team.

I have checked the template folders and found the following:

KwizCom_KSME folder
KwizCom_SLFE folder

___KSMEDefaultTemplates.ascx
___SLFEDefaultTemplates.ascx

I have deleted them and the error has gone away. So thank you. It would be good if KwizCom have a clear instruction uninstalling it from SP 2010 though.
At the moment, this is what I got from the User Guide:"Retract and delete the solution using SharePoint central admin or by using stsadm/powershell command line."

As we had to install multiple .wsp for the List Forms Extension, it is not clear which one should we uninstall first and whether we should deactivate and uninstall the feature first before we uninstall the solution.  Those confusions could be the reason why we didnt have a clean uninstallation.

Anyway, just a suggestion. Thank you and the support team for the prompt reply.

Regards,

leeta

Hi,

Unfortunately we do not have any control on SharePoint's deploy/retract solution process. Seems something went wrong in your servers during retract and the files were not remove properly.

Thanks,

Igor,
