Theme looks wrong on mobile devices


I am having an issue where viewing my blog on a mobile device looks completely different than the regular theme. I don’t think I was having this issue a few days ago. Did I edit something incorrectly?
How can I fix this?

Hi @ksiciak,

I hope you are well today and thanks for posting here.

I visited your shared site on mobile and it’s displaying fine for me like activello theme demo site

Could you please tell me a bit more in detail what’s the issue you are facing so that i can troubleshoot it?

Also is the activello theme demo site working fine for you?

Best Regards,
