The font color of the headings is being changed to black because of FandomizedHeadings which's being imported on Wikia.css. It uses a class to properly handle the dark theme wikis, which's not available on UCP anymore. It also uses other classes that aren't available on UCP as well, so basically, it doesn't work on UCP on the most part. You can remove it from the imports to fix the issue; it can be found on Wikia.css on the second line.

And as for links, I don't see what's the issue there. Am I right to assume that issue got fixed? :)
