We have a site which has been using the hosts ssl connection as their https server.

Ex: https://subdomain.hosts-site-name.com

Apparently the setup had been working but now all of the secured pages; login, checkout, my account pages etc. load a 500 error page.

What is really odd is, I set ENABLE_SSL to false in both configure files. That did not stop the store pages from using the https server url. Next I replaced the HTTPS_SERVER url with the actual zen cart http website url in both configure files. Still no change on the front end.

The host is saying misconfiguration somewhere and "upload configuration for the shopping cart"

The configuration changes I have made do not affect the front end. Any ideas what could account for this?

Wondering, if I was in the correct ftp account I made some text changes to the define_main_page.php file. The text change does not show on the home page BUT I can see the text change I made in the admin define page editor, so I know I'm in the correct ftp account. The server IP hadn't been changed.
