Frozen stream page

Hello, I've got a wierd issue after I made some changes. Before I rollback to a previous backup (that would undo even the working changes) I'm hoping there is an easy fix.
The issue: I can log in, and see posts, but I can only click on other users profile links and menu items. Every other click is worthless (the 3 dots on the right, the textbox,
the "Display" dropdown menu, the buttons Like, Comments, Share... they just don't work).
When I get at the bottom of the page, instead of loading older posts it shows a "More" button, that doesn't work if I click it.
I have the feeling it's some trigger I pulled wrong. Is there some kind of easy fix?

EDIT: I noticed that when I click on buttons I get javascript:void(0); error
EDIT2: I even updated joomla from 5.2.1 to 5.2.3. I don't know if the issue was showing prior to the update, it certainly shows now.
 

That generally means you've a fatal javascript error causing the javascript to fail. Press F12 and click the Console tab in your browsers developer tools. Now refresh the page and see if there's any errors. They're generally colored red.
