1337 // Bugfix: Try to defer OS errors about session.save_path and ACCESS_LOG,
1338 // so they don't prevent IE from partially (or not at all) rendering the
1339 // page. This should help a little for the IE user who encounters trouble
1340 // when setting up a new PhpWiki for the first time.

1348 // Localization bugfix: For wikis where English is not the default system
1349 // language, make sure that the authority error message (i.e. "You must
1350 // sign in to edit pages in this wiki" etc.) is displayed in the wiki's
1351 // default language. Previously it would always display in English.
1352 // (Added call to update_locale() before displaying any messages prior to
1353 // the login prompt.)

1356 // Bugfix: For a non-english wiki or when the user's preference is not
1357 // english, the wiki would always use the english ActionPage first if it
1358 // was present rather than the appropriate localised variant. (PhpWikis
1359 // running only in english or Wikis running ONLY without any english
1360 // ActionPages would not notice this bug, only when both english and
1361 // localised ActionPages were in the DB.) Now we check for the localised
