I have been stuck on this error and am unable to solve it since the past few days. I have googled all I could, but none of the solutions seem to work for me. I'll go through all the steps I've done and hopefully, someone might be able to catch a mistake. Also, I've been developing with SharePoint for quite a while now, but still a beginner in some parts.
I have created my site in my SharePoint and created a new Site Collection for it. I deployed my web part with the following command in powershell:
Update-SPSolution -Identity xxxxx.wsp -GACDeployment -LiteralPath "C:\Users\username\Desktop\xxxxx.wsp"
I then go to my created my site and add the web part. Which alerts me with the following message.
I tried many solutions including,
- I checked if my Web part is declared as Safe in the web.config or my root site. It looks like this:
<SafeControl Assembly="xxxxx, Version=188.8.131.52, Culture=neutral, PublicKeyToken=4a87d6fcb45f5672" Namespace="xxxxx.xxx" TypeName="*" Safe="True" SafeAgainstScript="False" />
- My class name SharePointProject1.WebPartName is declared as public.
- I've deployed the web part to the GAC by using -GACDeployment
- The namespace name is same as it is defined in my project.
I also checked my Application Logs in the Event Viewer, but there are no errors mentioned there as well.
After all this, I have a feeling maybe it might be a problem with my User Profile Service creation, though I'm not very familiar with this side of SharePoint.
I followed these two tutorials to create a User Profile Service & the My Site: http://sharepointgeorge.com/2010/configuring-the-user-profile-service-in-sharepoint-2010/ http://www.boostsolutions.com/blog/how-to-create-configure-my-sites-in-sharepoint-2010/
Any help would be really appreciated. Thanks!
