HI @avivtech
Thanks for posting about this – definitely weird behavior!
I looked through your site and it looks like there is some custom CSS in your home page that has a small typo for the closing tag.
As of a couple weeks ago, we’ve gone hands off with custom code (read more here).
Mainly this change affects closing tags for custom code – before the Designer would check custom code and embeds to make sure there were the correct closing tags but this was causing more harm than good in some cases. This is most likely why the site was working fine before the change was implemented.
I hope this helps!
