When trying to create a new page using the New Page/"Create" panel, it
always displays a message that the the page already exists. Other means of
creating a page work fine, like using the "Create Page" menu item of the
space or typing the new page name in the URL.
I have an XEM 2.3.28624 installation with two XE instances set up using
Path-based resolution. This error is occurring in both XE instances.
Steps Taken
1. visit the wiki
http://server1/xwiki/wiki/mywiki/
2. Type in any value into the Name field on the "Create" panel
3. click the "Create" button
The page with "This document already exists" is shown.
