Resolution: Not a bug
Affects Version/s: 3.3
Fix Version/s: None
Component/s: Wiki (2.x)
If the user enters a newline character in a title of a subpage, then the page would not be linked correctly to the mainpage.
[[ Hello my nice
This would create a wiki_pages entry with the title "Hello my niceWorld" with the result, that the entry in wiki_links would not be updated to be linked to the correct page.
Probably one solution could be to replace the newline character with a space in the mainpage and the subpage title.
Or another approach is, to remove these newline characters from the mainpage, if the are in a subpage link.
