1353 // Fixes permission failure issues. With PagePermissions and Disabled Actions when user did not have permission WIKIAUTH_FORBIDDEN was returned. In WikiUser this was ok because WIKIAUTH_FORBIDDEN had a value of 11 -- thus no user could perform that action. But WikiUserNew has a WIKIAUTH_FORBIDDEN value of -1 -- thus a user without sufficent permission to do anything. The solution is a new high value permission level (WIKIAUTH_UNOBTAINABLE) to be the default level for access failure.

1504 // * changed stored pref representation as before.
1505 // the array of objects is 1) bigger and 2)

1527 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1528 // so they don't prevent IE from partially (or not at all) rendering the
1529 // page. This should help a little for the IE user who encounters trouble

1539 // language, make sure that the authority error message (i.e. "You must
1540 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1541 // default language. Previously it would always display in English.

1543 // the login prompt.)

1546 // Bugfix: For a non-english wiki or when the user's preference is not
1547 // english, the wiki would always use the english ActionPage first if it
1548 // was present rather than the appropriate localised variant. (PhpWikis
1549 // running only in english or Wikis running ONLY without any english
1550 // ActionPages would not notice this bug, only when both english and
1551 // localised ActionPages were in the DB.) Now we check for the localised
