Issue with Portal links with the Reflect theme

I’m having a real issue with the /#/portal/ links on my site.

I currently use the Reflect Theme, and my issues have been so extensive that I’ve needed to use custom JS to override the theme links.

Can somebody please debug and help me understand why my portal links don’t work?

An example included here, scroll down to comments and click ‘sign up now’ or ‘sign in’. Neither link works.

Example: 🇫🇷 Ultimate guide to France's squad for UEFA EURO 2024

The other links on my site to the portal links (e.g. Subscribe) were overridden using JS.

This has been fixed.
