Hi Jon, I seem to have the above problem and the solution link you provided, brings a 404 error from your site.
The forum shortens the above link - this is the problem where, in x-cart you select re-direct from https: to http, and it brings up a 404 error with CDSEO in the address bar.
I assume its a good idea to redirect from secure pages when they are not needed??? Do you have the solution available somewhere else now?
Thanks!
EDIT: Sorry, just found the link from your page here:
