It's not that big of a deal. Just login to the server and do a simple find and replace. The basic syntax is:
Code:
grep -rl "oldstring" . |xargs sed -i -e 's/oldstring/newstring/'
And example might be:
Code:
grep -rl "http://affiliatelink.com/track/affiliatecode/" . |xargs sed -i -e 's/http:\/\/affiliatelink\.com\/track\/affiliatecode\//https:\/\/affiliatelink\.com\/track\/affiliatecode\/'
I just did that quickly so I may have missed an escaped character. You simply need to use the first example, and then escape any special characters, including periods and slashes.
