Hi Richard,

Other modules, such as HTML, load without issue.  I'm using the plain vanilla DNN 9.2 installation and the generic skin.  This morning, I uninstalled the extension and reinstalled a fresh build.  The error in Admin logs shows:

AbsoluteURL:/API/PersonaBar/Extensions/GetInstalledPackages

My next step would be a fresh install of DNN but wanted to find out if there are any issues I can easily remedy without having to do so?  Thanks so much for your help and guidance.

This is still an issue for me.  I think it's because I was implementing IUpgradeable in my FeatureController class.  I've tried commenting out this implementation and removed Upgradeable as a supported feature.  However, when I try to comment out the following lines from my manifest, the module won't even install:

<eventMessage>

            <processorType>DotNetNuke.Entities.Modules.EventMessageProcessor, DotNetNuke</processorType>

            <processorCommand>UpgradeModule</processorCommand>
