1348 // renamed mayCheckPassword => mayCheckPass
1349 // fixed recursion problem in WikiUserNew

1352 // Revision 1.106 2004/01/26 09:17:49 rurban
1353 // * changed stored pref representation as before.
1354 // the array of objects is 1) bigger and 2)
1355 // less portable. If we would import packed pref
1356 // objects and the object definition was changed, PHP would fail.
1357 // This doesn't happen with an simple array of non-default values.
1358 // * use $prefs->retrieve and $prefs->store methods, where retrieve
1359 // understands the interim format of array of objects also.
1360 // * simplified $prefs->get() and fixed $prefs->set()
1361 // * added $user->_userid and class '_WikiUser' portability functions
1362 // * fixed $user object ->_level upgrading, mostly using sessions.
1363 // this fixes yesterdays problems with loosing authorization level.
1364 // * fixed WikiUserNew::checkPass to return the _level
1365 // * fixed WikiUserNew::isSignedIn
1366 // * added explodePageList to class PageList, support sortby arg
1367 // * fixed UserPreferences for WikiUserNew
1368 // * fixed WikiPlugin for empty defaults array
1369 // * UnfoldSubpages: added pagename arg, renamed pages arg,
1370 // removed sort arg, support sortby arg

1376 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1377 // so they don't prevent IE from partially (or not at all) rendering the
1378 // page. This should help a little for the IE user who encounters trouble
1379 // when setting up a new PhpWiki for the first time.

1387 // Localization bugfix: For wikis where English is not the default system
1388 // language, make sure that the authority error message (i.e. "You must
1389 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1390 // default language. Previously it would always display in English.
1391 // (Added call to update_locale() before displaying any messages prior to
1392 // the login prompt.)
1394 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
1395 // Bugfix: For a non-english wiki or when the user's preference is not
1396 // english, the wiki would always use the english ActionPage first if it
1397 // was present rather than the appropriate localised variant. (PhpWikis
1398 // running only in english or Wikis running ONLY without any english
1399 // ActionPages would not notice this bug, only when both english and
1400 // localised ActionPages were in the DB.) Now we check for the localised
