I suggest taking a look at your html sanitization settings make sure html isn't allowed in markdown settings.
Next step would be to move the other 2 topics from that category and check if you still see broken markup.
I've encountered a problem. After I log into my website and I click on the logo or any other icon, I get stuck with a loading screen as shown below. I waited about 3-4 minutes but it just keeps on loading. I then have to close the tab and go to my website again for it to work.
@PitaJ This is what I have
@julian This is before the login
Now that I try to recreate that issue, it's working fine.
