Overview of the Issue
If you have a page that you initially created in Gutenberg, there may be remnants of Gutenberg blocks inside of it.
This is usually visible if you check with the Gutenberg Code View. To view it, go to the post, click on the 3 vertical dots next to the gear icon, and then select Code Editor. You can also use the shortcut Ctrl + Shift + Alt + M.
This is an example of the content that you might have trouble with:
<!-- wp:heading {"level":1} -->
<h1>Test</h1>
<!-- /wp:heading -->Workaround
This issue is fixed. Updating to the latest version solves it on your site, so you only need this workaround if you can’t update yet.
As a workaround, you should create a new post and add the contents again, but make sure that they don’t contain Gutenberg blocks.
