Content Query Web Part error “Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.”

Well this error occurs when you have not configured AAM (Alternet Access Mapping)for the particular web application. Suppose if the internal URL is http://server:81 and you are accessing the URL out of the server by mapping the DNS, then you will face this issue in the web part. SO, to resolve this issue just configure the public URL for the http://server:81 to like http://www.sample.com/.net etc.

STSADM on adding wsp Error “Object reference not set to an instance of an object. sample.wsp: The Solution installation failed. ”

Hi, Well today when I was deploying the SharePoint site I got the above error. Well on first look it seems that this is SPSite or SPWeb or we can say that this object model issue. But I got info from googling that this issue comes due to permission on the content db from which the user is deploying the WSP by using the STSADM command. Well I looking for more options for that but it seems that the issue is due to user permission on content db.

And guess it works. Well when you dont have permission on the Admin_content db then this issue will occur.

The below command will also help you check the permission

stsadm -o enumsites -url http://yoururl
