Can't add/edit products since installing ssl certificate

So I updated a product under Catalog>categories/products, and when I hit the preview button a security warning popped up saying:
Security Warning

Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party.

Are you sure you want to continue sending this information?

I said continue and it showed no product and a price of 0.00, then deactivated the product. I cannot delete that worthless product, nor can I add a new product because it keeps giving me that security warning and posting nothing. I just purchased an ssl certificate, which may be the problem, but why would an ssl certificate destroy this?

If anyone has any idea why I cannot edit/add products please help! It is making me :censored: crazy! The site is https://www.atvauger.com/store

Is add/edit products the only place where you can't make changes? Have you tried modifying any other configuration settings?

In looking at trouble-shooting ssl issues, I would first check that the ssl paths set in admin/includes/configure.php are set correctly and I would make sure that the ssl host also matches.

For example,

If your SSL host is

https://domain.com

then you might have a problem trying to resolve

https://www.domain.com

I just visited your site and got a domain mismatch error when I clicked the link to login. Your ssl certificate is for https://www.avtauger.com, but your configure.php file is pointing to avtauger.com (without the www.)

Both config files have to be updated:

/store/admin/includes/configure.php

example:

define('HTTPS_SERVER', 'https://www.atvauger.com');
define('HTTPS_CATALOG_SERVER', 'https://www.atvauger.com');

/store/includes/configure.php

example:

define('HTTPS_SERVER', 'https://www.atvauger.com');

I will try that and let you know how it goes. Thank you so much for responding quickly Tina.

That solved the problem I was having with the css not working in IE and Safari, so thank you for that. However, when I try to log in to the administrator, upon hitting login it acts more like a reset form button instead of logging in. So I don't know if the add/edit products thing was fixed or not. And the add to cart button has the security error, which makes it not function. The cart problem is probably similar, in that a www needs added somewhere. Do you know where I need to add that? Thanks again for the assistance.

Well, it works now. But not in my Firefox browser. It must be a cache thing and I'll figure that out. Thanks again for your help Tina!
