Problem with URL's for previous_posts_link and next_posts_link

I’m having an issue. I’m hosting a wordpress on https://www.badsequels.com/tastylies/. I’m forwarding the domain TastyLies.com, with masking, so that address.

WordPress URL is set to htp://www.badsequels.com/tastylies/
Site url is set to: https://www.tastylies.com/

Everything works. All of it. Except the older and newer posts at the bottom of the page. All of the category and post links point to https://www.Tastylies.com/?p=???? – The ???? being the post number. The older and newer pages links point to https://www.tastylies.com/tastylies/?paged=????

How do I get rid of that extra /tastylies/? I’ve looked everywhere and for the life of my I can’t figure out where previous_posts_link_ and next_posts_link are defined. Please help?
