My b2evolution Version: 1.9.x

G'day everyone

My wife had starting using b2e by editing some of the pages, and then we wanted to create a simple URL for visitors. Now here's my setup:

The initial page (the one with the admin link at the bottom of the page) was gesin.ijlant.com. I noticed that the admin login page was gesin.ijlant.com/admin.php, so I figured I could just use gesin.ijlant.com as the blog URL itself. So I changed it to that. Well, now we have this problem:

If I visit gesin.ijlant.com/admin.php, I get a login page, but when I log in, b2e redirects to ijlant.com/admin.php (which doesn't exist), and gives me a 404. So, I'm effectively locked out of the admin module.

I have no idea how this happened. I didn't change the admin URL.

Any suggestions for other blog software that won't do this?

Thanks
Samuel
