1481 // * changed stored pref representation as before.
1482 // the array of objects is 1) bigger and 2)

1504 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1505 // so they don't prevent IE from partially (or not at all) rendering the
1506 // page. This should help a little for the IE user who encounters trouble
1507 // when setting up a new PhpWiki for the first time.

1516 // language, make sure that the authority error message (i.e. "You must
1517 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1518 // default language. Previously it would always display in English.
1519 // (Added call to update_locale() before displaying any messages prior to
1520 // the login prompt.)
1522 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
1523 // Bugfix: For a non-english wiki or when the user's preference is not
1524 // english, the wiki would always use the english ActionPage first if it
1525 // was present rather than the appropriate localised variant. (PhpWikis
1526 // running only in english or Wikis running ONLY without any english
1527 // ActionPages would not notice this bug, only when both english and
1528 // localised ActionPages were in the DB.) Now we check for the localised
