I am evaluating different versions of confluence, and I have successfully installed and run zipped version of confluence standalone 4.2.1 and 4.2.2 When I tried the same for 4.1.2 I couldn't get passed the login page. I've followed the tutorial for installation, the same as for other two versions but when I come to starting using confluence I am always redirected to login page. When I try non existing user I get the message that user/password is not valid, but for admin/admin (or whatever other user I set previously) I get empty login fields shown again with no additional message displayed. Same happens for included as well as for external mysql database that I use.
Most interesting thing is that now the same happens for other two (4.2.1 and 4.2.2 installations as well) and I can not log in there as well.
Any help will be most appreciated.
