"All Files" has suddenly stopped working in my SharePoint Designer 2013. It doesn't even try to load files. I just says "There are no files in this view that match the current filter settings...". Clicking Masterpages will show all masterpages as expected. Clicking back to "All Files" does nothing. Clicking the refresh button does nothing.
I am an Office 365 Global Admin. I am the Site Collection Admin. This is true for all Site Collections on my Tenant. It worked fine for 3 years and just stopped this week. I have rebooted. I have completely uninstalled SharePoint Designer. I have reinstalled this time to 64 bit. I have installed the Service Pack 1. I am assuming there is some sort of cached setting or registry setting as the problem persisted after a complete uninstall/reinstall.
Somebody must know. Please help!
