Td-composer not editable, white space above header and theme panel gray. Help!

Hi, I have several problems on my website after updating the theme and wordpress to the latest version. I uninstalled all the plugins that could cause conflicts, contacted my hosting service several times and we don´t longer know what might be causing the following issues:

1. There is a blank space above the site header, a space that is misaligning the header and footer social network icons.
2. When I open the theme panel, half of it is the normal color and the rest is gray, with the same white space at its top.
3. When I am editing a page using tagdiv composer, the page opens for editing, but the title fields are not editable and I cannot save any other changes made.

I have the screenshot of all the screens with the errors, but I would really appreciate if you looked at the website to try to understand what is going on (https://www.asviagensdetrintim.com.br/). I’ve been using the Newspaper theme for a few years, I’ve been using it on other websites, and I’ve never had this kind of problem.

Thank you
