I am trying to create a new page by going to "Site Actions/new page" first it gives me a little modal page which contains two buttons Create and Cancel and following message:
In order to create wiki pages on this site, there must be a default wiki page library and a site assets library. Would you like to create those document libraries now?
When I click on Create button it generates a new modal which says:
Error A list, survey, discussion board, or document library with the specified title already exists in this Web site. Please choose another title.
I haven't chosen or entered any title. Appreciate any kind of advice.
