Site pages mess

Hello,

I have WP6.5.2 and the Theme v4.6 and Woocomerce v8.8.2. I also use child theme. I did account backup from my host provider. Right after that my site pages get mess abnormal narrow and missing images. The admin site is good, and the site becomes normal while login the admin site. that’s weird.

Can you please advise how to check and solve this problem? Thank you in advance!
