How to Renable Password Save for a Specific Website?

I mistakenly told IE 11 to NOT remember a password for one specific web site, and I want to reverse that decision for the site. All other sites that I have saved a password for are working fine, and I also want IE to prompt me to save a password for the one specific site I messed up on! Help?
