Update: The page code can be accessed via my page URL. I'm unsure where the issue lies. Your assistance is appreciated.
Issue:
Initially, when clicking on the chess puzzles page, everything works fine. However, upon re-clicking from the homepage, the boards disappear.
Demonstration:
This is the homepage.

When you click on a player's picture, it takes you to this page where the boards are visible.

If you then click on the link to go back to the puzzle list, you are directed back to the homepage.
Subsequently, clicking on any player's photo (or even the same player's photo) results in this display.

After this point, none of the puzzle links function properly.
You can investigate further at chess-puzzle.com.
Additional Information:
The website utilizes Cloudfare. Despite deactivating Cloudfare a few minutes ago, the issue persists.
I've checked the JavaScript and it appears to be correct.
My site only has one CSS file (mycss.css). All other external files were included with the software package.
I am uncertain which code to share as I am unsure of the root cause of the problem. If needed, I can provide specific code sections upon request.
Any guidance or solutions would be greatly appreciated.
