Hi. I'm having a problem logging into the Wordpress control panel on a particular site (www.agncn.org). I am not a WordPress expert by any means, although I do have a decent amount of online experience (I'm a longtime Expression Engine user).
When I try to login to the control panel by visiting http://www.agncn.org/wp-admin/, I am automatically forwarded to http://www.agncn.org/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F. If I go to http://www.agncn.org/login.php, I get the login form, but when I try to login, I am forwarded to that same upgrade.php url.
I have tried renaming the plugins directory (thinking that perhaps there was a corrupt plugin causing the problem), but that didn't help. I also tried renaming the .htaccess file in the wp-admin directory, that but that didn't help either.
Any ideas on why something like this might be happening?
Thanks in advance for any help you can offer - I really appreciate it. I was also planning on asking you some WordPress security questions, but I noticed that you have a video series on WP security, so I'll probably consume that first.
