Text and buttons disappeared!

The text and buttons of the website disappeared. On mobile, desktop and tablet. In the preview mode and in the published mode, when people visit the website, there's no text and buttons there. Only empty rows with background images.

When editing in the visual builder, I can see the text and buttons when I hover over it. So they're still there, but it's like there should be a button to click and the text is visible again without disappearing when you're not hovering over it.

I also tried the Theme Options > Builder > Advanced > 'Clear' button on the Generating Static CSS stuff, but it did not make any difference, except for the layout of the Menu coming back (that suddenly changed back to the basic layout from the theme).

I have updated Divi Builder and Wordpress, but the issue appeared even before that..

It's like there's a bug in Divi or something.

Please help!

 

Thank you for the tip!
I tried and it worked with 1 row, but the problem is that it appears on the whole website. With other rows, the text still didn't show permanently until I hover over it (and that's only in the edit mode, because on the published website, you can't see text at all even if you hover over it).
And some rows already had 100% opacity, and they're still not visible until I hover over the place the text is.
I think I should change a setting somewhere for the whole website.
Or is there a code I can insert or change in the theme editor?
Thanks in advance!
