Position of recent news and search on blog

Hello,

something went wrong on blog page and "recent news" module and search are positioned beneath the content.
Please check sanabilis.mojastran.net/blog . Screen print attached. Any idea how to solve this problem. I have hidden the date on the left of blog articles, but this problem was there before that.

Regards

Hello,

Perhaps you break the website's HTML when you inserted some content. Try to validate your page here and fix all the errors, especially those related to layout (div, li...).

Thanks

It seems it was the first article before "read more" that broke the site.
I deleted some div-s and non-breaking spaces - that solved the problem.

Thanks
