Thread:Project:Support desk/manual (as in labor) wiki creation with 1.17

I am trying to install a new wiki by hand by following the instructions at Manual:Security. I am using a LocalSettings.php generated by the 1.17 installer for a different wiki. I modified the site name, database and script path. I granted rights to the same mysql user on new database. I get a blank page at the url after completion of all steps. No error feedback at all. I am using mediawiki 1.17 with mysql 5.1.49 and php 5.3.3 Any ideas appreciated.
