I want to upgrade so that I can offer visual editor. CentOS 6.6, 64 bit, postgresql database, php 5.3.3 I followed the instructions and using a browser: * go to wiki//mw-config/index.php, language is OK so I click CONTINUE * next page I am prompted for the upgrade key that I copy/paste, CONTINUE * Environmental checks. Other than a warning about 'older version of the ICU project's library' all is OK, CONTINUE * Database settings, enter username/password, CONTINUE * Name page. I enter wiki name & admin details, select 'Im bored', CONTINUE * Install page, CONTINUE * I get database error: Error: 42P07 ERROR: relation "mwuser" already exists It appears to be trying to do a fresh install rather than an upgrade. But it asked for the upgrade key earlier ? As root at the command line I run & get: # php maintenance/update.php MediaWiki 1.24.0 Updater DB connection error: No database connection What am I doing that is wrong ? -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
