SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I have successfully added a provider hosted app to the app catalog.

However, when I go to the main site, then go to the "gear" icon, and select "Add an app", it gets stuck at "Loading" forever.

If I view javascript errors, In IE10 see:

SCRIPT5007: Unable to get property 'className' of undefined or null reference 
ScriptResource.axd, line 5 character 59249

And in FireFox I see:

Error: TypeError: b is null
Source File: https://blah.test.net/ScriptResource.axd?d=SsARyFD3_rQCMDLd6IgfYaxJnLFnvxkC1Xtj47fGS-nQa4JCl2bx2MyfQ9rvUL53P-WbzGFUoUC-lVUcbrX5lHQ6RNC1BnccNHsuuoi76QciKDMPANw6dKkz8pgiX5fuW6ysOtL6n0GoF-4xlZkviLwqYgxj75pJxS4GjF0C38uNL2diSVl0z48saetHiQmE0&t=6119e399

Line: 5

I retried the request, then grabbed the most recent logs via SharePoint management console with the command:

get-splogevent -starttime (get-date).addminutes(-1) | fl message > error.txt

Examining the error logs, I can't find any smoking gun.

How can I fix this so that I can add an appmodel app to a publishing site?

Turns out there is a bug in the SharePoint master designer in SharePoint 2013 RTM.

See: http://blog.drisgill.com/2012/12/design-manager-bug-sharepoint-2013-rtm.html

Basically, you have to ensure that your master page contains specific items.

Thanks Nathan. Just removing Visible=False from DeltaPlaceHolderLeftNavBar fixed my issue. MS should have a fix for this as its been existing since 2012 –  Colbs Jul 15 '14 at 14:58

Specifically, if you are using Sharepoint Designer 2013, your code should look like this (notice Visible="false" has been removed)
