Recently, I was tinkering around with my website and trying to make it load faster. My host is Hostinger and I have LiteSpeed Cache, as well as connecting Cloudflare. I know literally nothing about coding and programming, so I was just following tutorials for litespeed cache and got lost. Now, my website's pages won't load properly after you click around. I really don't know what happened and I just want it back to normal.
The link to my site is: sparking-global-leaders.org
Here are some pictures to show what is going on because I cannot describe it well. This happens when I click on another page. It does work if I reload it however. After click around for a bit, I even encounter this menu. Can somebody please help me?
