I've installed the mediawiki and ran through the config process, but when I go to http://localhost:8080/mediawiki/index.php, (which is where I installed everything) I get a MediaWiki internal error. I am using PostgreSQL 9.1 on Windows 7, using an apache 2.2.20 server and php v. 5.3.8. The page suggests to run the update.php in the maintenance folder, which produces errors also, but closes before I can read them. Below is what the index.php shows: MediaWiki internal error. Original exception: exception 'DBQueryError' with message 'A database error has occurred. Did you forget to run maintenance/update.php after upgrading?

When I query the objectchache table in the database, I get 2 records, but none have the keyname = 'my_wiki:messages:en' Any help would be greatly appreciated. Thanks.
