I'm getting the same problem, but now instead of being when I tried to install, it's happening when I try to login or register.
My install version is wpmu-2005-08-26 and when I don't have the .htaccess in the directories I'm getting this:
Fatal Error
Database Tables Missing.
The table wpwl::wpmu_site is missing. Delete the .htaccess file and run the installer again!
Please check that your database contains the following tables:
wpmu_blogs
wpmu_users
wpmu_usermeta
wpmu_site
wpmu_sitemeta
wpmu_sitecategories
But, the thing is: the tables were created by the install. I even was able to create the admin login. I can't figure out what is wrong.
I tried to put the .htaccess and now I'm getting this:
Warning: main(/my_path/mublogs/wpmu-settings.php): failed to open stream: No such file or directory in /my_path/mublogs/wp-config.php on line 86
Fatal error: main(): Failed opening required '/my_path/mublogs/wpmu-settings.php' (include_path='.:/usr/local/lib/php') in /my_path/mublogs/wp-config.php on line 86
Any ideas???
