1502 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1503 // so they don't prevent IE from partially (or not at all) rendering the
1504 // page. This should help a little for the IE user who encounters trouble
1505 // when setting up a new PhpWiki for the first time.

1514 // language, make sure that the authority error message (i.e. "You must
1515 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1516 // default language. Previously it would always display in English.
1517 // (Added call to update_locale() before displaying any messages prior to
1518 // the login prompt.)
1520 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
1521 // Bugfix: For a non-english wiki or when the user's preference is not
1522 // english, the wiki would always use the english ActionPage first if it
1523 // was present rather than the appropriate localised variant. (PhpWikis
1524 // running only in english or Wikis running ONLY without any english
1525 // ActionPages would not notice this bug, only when both english and
1526 // localised ActionPages were in the DB.) Now we check for the localised
