https not working paypal pro?

My https use to work,
I set up paypal pro today and it wont work at check out,
Is there a setting in paypal pro i need to change,
The checkout works fine but no https which is not good secure,
Link to my site http://youniverseonline.com/
Thanks,

That has nothing to do with "paypal pro".
You've not enabled SSL in your configure.php files.

It works when you put https://youniverseonline.com/
My webhost said they configured it for me when they installed it,
I just contacted them and ask them to take a look,
Just looked in my configure.php file and its set to true,
The settings look all correct,

When I go to your site WITHOUT using HTTPS, and click on your Log In link, a properly configured Zen Cart site will switch to using the HTTPS address automatically. Yours didn't.

So, that tells me that your configure.php file settings are not correct. ie: ENABLE_SSL is not set to 'true', and/or the HTTPS_SERVER address doesn't have an https URL in it.

All my setting seem to be set up correct,
My host checked it on http://www.sslshopper.com and said it seems to be working correct,
I asked them to double check the php file,
Hoping to get this resolved soon,
Thanks,

 define('HTTP_SERVER', 'http://youniverseonline.com');
  define('HTTPS_SERVER', 'https://youniverseonline.com');
  define('HTTP_CATALOG_SERVER', 'http://youniverseonline.com');
  define('HTTPS_CATALOG_SERVER', 'https://youniverseonline.com');

  // Use secure webserver for catalog module and/or admin areas?
  define('ENABLE_SSL_CATALOG', 'true');
  define('ENABLE_SSL_ADMIN', 'true');

They told me enable ssl checkout was set to false,
Changed it to true,
Now its all working,
Good to go now,
Thanks,
