I have a urgent problem.
Sorry for any mistakes in English, I do not know the language very well.
Suddenly, my Template began to behave strangely. Everything on the site is in the wrong place. Interestingly, when users are logged everything is shown normal.
You can see: www.sebemnet.org.br

It seems incredible but all returned to work properly without me doing anything.
What happened? What could be the problem?

Dear Rafael

I checked your site and it is working
If you have problem again, please check your latest article, i think you was missing a close tag

Thank you.
