Where can we see the website in question?
This is the website: https://chainsawacademy.husqvarna.com/. Though, the issue can only be seen in the admin panel.
Which versions of WordPress and the Bogo plugin do you use on the site?
What other plugins and theme do you use on the site?
The theme is developed by my studio.
There are other plugins on the live site (BackUpWordPress, Redirection, Simple Page Ordering, UpdraftPlus, WP Rocket, Yoast SEO), but on our nearly identical staging site Bogo is the only plugin. I came to the conclusion that Bogo caused the problem because of this (the problem stopped on deactivating Bogo on the staging site).
WordPress Wysiwyg fields do not display content in the Visual tab anymore, they are blank. In the Text tab, content is still displayed.
I’m not sure what you are describing in those sentences. What exactly do you mean by “the Visual tab” and “the Text tab”?
Native Wysiwyg editors in WordPress allow you to edit in Visual or Text mode. Like this (notice tabs in the right corner):

WordPress 5.7 doesn’t natively support that editor.
Okay. Thank you for looking into it. Still, when I deactivate Bogo, the issue is resolved (tried it now again of course). It is quite strange.
