Hello
I tried to build ‘XWiki’ and copy a specific page, but error 400 occurred. I saw the name of the page that I copied to the menu and navigation panel, but when I clicked, the error 400 page reappears. I tried to log back into the admin account and delete the account from page index, but it is not deleted either. The same thing happens when I log in with my regular user account and admin account.
What should I do?
