I have one more question
I don't know why, but now I have two admin pages. And it's strange because I didn't add it. Can I just delete one folder? One of them is my page which I saved after installation and it's working fine, the second - no, have redirection problem(which I fixed only for my default admin url).
upd. Okay, just deleted it, looks like everything is fine. Only question where did this adminpage come from
upd2. Maybe after reinstallation. So maybe this why I had problem with redirections to inde page.
