I've got a reusable SP Designer workflow in SharePoint 2010, and I'm trying to edit the Initiation Form for it. I can open the workflow within SP Designer, click the form, and it opens in InfoPath. I then make the changes that I want, and try to Save/Publish it back to the server. When I do so, I get the following error:
The following URL is not valid: http://myserver.domain.com/sites/mysite/Workflows/My Workflow Name/My Workflow Name.xsn
I've tried looking in the SP logs, and don't see anything relevant at the time I try to publish the form. I can make the changes to forms on my dev box that has InfoPath installed locally. But when I take a site backup and restore onto the production server, then try to make any form edits using InfoPath on my client, I get the same error.
Any thoughts on what the cause might be and how I can resolve it?
