CMS 7.6 Edit page tree not loading

Hi, I'm having some trouble with a site i just upgraded from CMS 7.0 to 7.6 I also ran the VppToContentMigration tool. I'm able to view the site normally without any problems but in edit and admin mode I notice some errors.

I can log in to the EPi edit/admin mode but opening the page tree I only see the root node and the loading animation, but no pages are loaded. I'm still able to enter forms edit for the page i'm on. I also noticed that on the Admin page I get the same or similar error if I click on the button to set the start page for the site(right now it's set to Start[15] but I can't change it).

In fiddler I get one error when loading the edit page:

GET http://localhost:17001/secui/cms/Stores/contentstructure/?referenceId=1&query=getchildren&typeIdentifiers=episerver.core.pagedata&allLanguages=true&sort()&dojo.preventCache=1397649417640
500 Internal Server Error (text/html)

with a stacktrace like this:

Could it be the same as this: http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=85177&epslanguage=en ?

Thanks for your answer Erik, I looked at this but I can't find any duplicates, not sure if I'm looking in all the relevant places though. 

I'm able to create new blocks, but not new pages, I can click create new page and enter a name for it, but I don't get any suggested pagetypes so I can't complete the creation.

In admin mode database information I can see "Total number of pages in database 2467" so apparantly something is found. And under content type I can see all my page, block, media and system types. I was also able to create a copy of my startpage type but I still couldn't create any page even based on that.
