I can't get my management to load on a workflow I am building.
I have checked the box to allow workflows to be aborted, but the management page is blank.
Bumping this up, I have still been unable to figure this out.
Can you please post more detail? Perhaps the steps you're going through to see the blank page and more information on the workflow project?
Check the IIS logs to verify you're actually getting a 200/OK to the page.
I was able to work with Support to get this resolved:
The workflow management page will not work on .net CLR v4 framework in IIS.
Changing the AppPool to .net CLR v2 resolved the problem.
