I haven't run into this particular problem before, and it seems rather strange to me.
I'm trying to make some changes to a site. So, I go to Site Settings, of course. From there, under Look and Feel, I click Title, Description, and Logo. Instead of seeing what I expect, however, I get an error page that reads:
"Sorry, something went wrong. A list, survey, discussion board, or document library with the specified title already exists in this Web site. Please choose another title."
This confuses me. I'm trying to access the settings. Any ideas on how to get around this?
