- // Revision 1.101 2003/11/25 21:49:44 carstenklapp
- // Bugfix: For a non-english wiki or when the user's preference is not
- // english, the wiki would always use the english ActionPage first if it
- // was present rather than the appropriate localised variant. (PhpWikis
- // running only in english or Wikis running ONLY without any english
- // ActionPages would not notice this bug, only when both english and
- // localised ActionPages were in the DB.) Now we check for the localised
- // variant first.
