I have installed MediaWiki 1.1.0 on a Windows 2000
machine. Everything works well except for logins.
After I login, I get the "login successful" message.
Anytime I click to another page, the page still shows
my IP address, and when I edit a page, the revision is
associated with my IP address.
Have you enabled the file cache ($wgUseFileCache) or database messages
($wgUseDatabaseMessages)? I had the same problem with logins yesterday but
it seems to have gone away after I disabled them.
Regards,
Erik
