In Subsite, i click to Title or description, or Logo the URL : https://domain.com/sites/ABC/SUBSITE1/SITESITE2/_layouts/15/prjsetng.aspx
and occur a error as below
"A list, survey, discussion board, or document library with the specified title already exists in this web site. Please choose another title."
i try other page in site setting such as AreaWelcomePage.aspx that is fine. so only the prjsetng.aspx occur error.
how can i fix it. thank you very much.
