I am using WP 2.7.1 and have problems logging in since a couple of weeks. If I use my direct link /wp-admin/index.php, then I get the 404 message. However, I'm logged in and if I click on the link "Site Admin" it works after clicking once again or twice. I uploaded my files via FTP and noticed that there are missing some files (obviously) however, the same procedure happens again the next day.
I am not sure about the reason for this bahaviour. Is the provider's site (does the server really delete) or is there something what changes my pages?
Do you have similar experience with WP 2.7.1?
