Mohammad,
Thanks, but that didn’t work. We are using a child-theme, which is perhaps why you didn’t see all the folders.
Anyway, it appears that the issue is related specifically to the Swift Framework Recent Posts Widget Titles. All other theme functionality works.
I’ve removed, then re-added the Recent Posts widgets, moved them to other widget areas, but the problem persists.
I also uninstalled, then reinstalled Swift Framework 1.01, then updated to 1.10.
