MarketPress with Network Solutions SSL = NIGHTMARE

Okay so for the past few hours I have been trying to get ssl working correctly on a clients website.

They are hosted with Network Solutions and are using Authorize.net.

I have tried changing the Website address settings in Settings > General to https and have used the Wordpress HTTPS (SSL) plugin both to no avail. This is becoming extremely frustrating as I cannot figure out the problem.

When using the two above methods no assets are loaded on my site. No links in my pages are switching to HTTPS, The plugin even kills the backend of my site and doesn't load any assets as they all stay as http.

Does anyone have a solution to this extremely frustrating problem
