Blog module issue

Hi, I have an issue with my blog module.

When I go to the page including all my posts, sometimes it loads as it should, sometimes it loads but you can't see it. You can still click on the blog posts, but everything's white?

If I refresh, then it will appear, but then if I refresh again later, it won't.

I found people having the same issue, so I tried to replicate what worked for them :

• remove the animation
• use the safe mode
• disable Autoptimize plugin

But nothing worked.

Here's the page : https://vlourish.com/blog-en/

Thank you for your help!
