1. Changing the AJAX setting does nothing.
2. I've just noticed that the live site -
www.digitalguarddawg.com
- now also does this. There was a security patch issued a month or 2 ago. At that time I had a number of manual changes I didn't want to go through and redo, so opted not to install the update, but only apply the patch. Prior to that, I don't ever remember seeing this shipping charge appear.
I do have 2 US Postal Service manual shipping plugin rates specified, all built on weight and size. This is where the system gets $20 from, but I would like to know why it's putting it in there when there is a FEDEX option if you continue through checkout.
