I've recently completed updating a DNN 7.4.1 install to DNN 9.1.1 with some difficulties.
The steps I've followed were to 1st disable all scheduler tasks in the database directly as without that i was getting timeout issues.
Next I upgraded to DNN8 which went through fine after disabling scheduled tasks. Then I proceeded to update to DNN 9.1.1 which also completed successfully.
Post upgrade I've logged into my website and can see the Persona Bar, but none of the links/functions work. I can see the bar and hover to see the pop-ups and sub pages but clicking on anything results in the following error when viewing in chrome inspector.
I've looked on dnnsoftware.com and google for any similar problems but have only found 1 issue that sounds similar on dnntracker but don't see any patches/fix instructions there.

My errors are:
jquery.js?cdv=136:4 POST http://example.com/API/personaBar/UserSettings/UpdateUserSettings 500 (Internal Server Error)
send @ jquery.js?cdv=136:4
ajax @ jquery.js?cdv=136:4

r.handle @ jquery.js?cdv=136:3
Can this be related to some IIS setting that needs updating for GET/POST methods? Running IIS7, although I do have other DNN9 sites functioning fine on the same server, only they were fresh installs.
