Hi, im extremely new to WP, but i did manage to modify WP to my likings with very much easy.. anyhow my problem is that I cant login on my site through the iframe that wp is nested in. https://www.rrsk.net/home.html WP is running through a iframe on home.html but when i go in the long way, https://www.rrsk.net/wpblog/wp-login.php I can log in perfectly. Any idea to what is causing this?
