2017 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
2018 // so they don't prevent IE from partially (or not at all) rendering the
2019 // page. This should help a little for the IE user who encounters trouble
2020 // when setting up a new PhpWiki for the first time.
2022 // Revision 1.103 2003/12/02 00:10:00 carstenklapp

2029 // language, make sure that the authority error message (i.e. "You must
2030 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
2031 // default language. Previously it would always display in English.
2032 // (Added call to update_locale() before displaying any messages prior to
2033 // the login prompt.)
2035 // Revision 1.101 2003/11/25 21:49:44 carstenklapp
2036 // Bugfix: For a non-english wiki or when the user's preference is not
2037 // english, the wiki would always use the english ActionPage first if it
2038 // was present rather than the appropriate localised variant. (PhpWikis
2039 // running only in english or Wikis running ONLY without any english
2040 // ActionPages would not notice this bug, only when both english and
2041 // localised ActionPages were in the DB.) Now we check for the localised
