I finally got access through the ftp and had to shutdown all of the plugins. Eventually, I found this one plugin to be the culprit – All In One WP Security & Firewall. As soon as the security plugin is activated, the entire site becomes messed up and cannot open the login page.

I have shut it down and activated a different security plugin.

Do you have any recommendations for a good security plugin for the site? I have had a lot of issues with attempted brute attacks that have shut the site down for a week or more.

Thanks again for your assistance.
