FIXED: but leaving up here in case anyone else runs into this…
Recently, I updated my website by using Duplicator to make a copy on my local machine and using MAMP for servers. The site transferred properly, with a copy of the forum at localhost:8888/etc…
After altering the site, I again used Duplicator to push it back out to WordPress, following the instructions and everything transferred beautifully — except SP. While the main Forum page is properly seated in the website, every single one of the Forum topics, posts, images, etc… now references http://localhost:8888/ in the paths.
What do I need to do to get the Forum transferred back properly and back up to its fully glory?
EDIT: I fixed it by updating the Forum permalink in the WP Integration area of the Forum setup. Sorry for the stupid post : (
