[General] Problem with theme? Thread shows blank

[Fours4]

This user has been denied support.

I'm looking to use a new theme which recently got released for free (by the owner), although it has a couple of issues, after mentioning it to the owner, he is sure that there isn't an issue with the theme, I've tested it on multiple installations but have the same issues.

Theme link: https://leak.rip/themedemo/

If you click on the thread, it just comes with a blank page.
https://leak.rip/themedemo/showthread.ph...pid=1#pid1

Also shows both logged in and logged out data at the top bar of the forum.

Anyone know a fix?
