Hello, the sidebar completely moved to the bottom and I can't change the location, tried left or right, when I select left it goes up, when it's right it's in the bottom, right and left are completely broken and unselectable.

Where is it you are seeing this? I am not seeing any issues with your site at present

Right here

Most of the time this is caused by some broken HTML code.

In this case the broken html is in your Page builder block at the top. You need to review that code

This issue happens on all the themes, not just the default, is everywhere

You have that block on all themes, not just default. So you would indeed have that issue everywhere

And what block is that? Where is it located?

It's the announcements block you have placed at the top of your site. That is what is breaking your layout. 

Note this can also happen due to google ad code, so you might need to check & update whatever code you're using from google and/or change it to a google responsive ad code instead.

It can of course. Anything at all that adds or changes your layout could cause issues if not done correctly

I should clarify that I mean it did happen with google ad code on my site (and not the announcement block like the OP) in case anyone else had the same problem but didn't have an announcement block. I'm not blaming Invision for breaking things that aren't anything to do with Invision's code/updates.

Thanks for the input and clarification!
