1424 // * changed stored pref representation as before.
1425 // the array of objects is 1) bigger and 2)
1426 // less portable. If we would import packed pref
1427 // objects and the object definition was changed, PHP would fail.
1428 // This doesn't happen with an simple array of non-default values.

1447 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1448 // so they don't prevent IE from partially (or not at all) rendering the
1449 // page. This should help a little for the IE user who encounters trouble
1450 // when setting up a new PhpWiki for the first time.

1458 // Localization bugfix: For wikis where English is not the default system
1459 // language, make sure that the authority error message (i.e. "You must
1460 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1461 // default language. Previously it would always display in English.
1462 // (Added call to update_locale() before displaying any messages prior to
1463 // the login prompt.)
1465 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
1466 // Bugfix: For a non-english wiki or when the user's preference is not
1467 // english, the wiki would always use the english ActionPage first if it
1468 // was present rather than the appropriate localised variant. (PhpWikis
1469 // running only in english or Wikis running ONLY without any english
1470 // ActionPages would not notice this bug, only when both english and
1471 // localised ActionPages were in the DB.) Now we check for the localised
