Edit a page or create a new page on my website with Toolset Types enabled.
Link to a page where the issue can be seen:
N/A. This is a problem with the editor, not the front-end.
I expected to see:
The block editor.
Instead, I got:
The classic editor. If I deactivate the Toolset Types plug-in, this issue goes away. Interestingly, it is only an issue for pages. The block editor works fine with posts.
This wouldn't be a huge problem except that there's not a good way to create a new view without access to the block editor on a page.
Types allows you to specify whether the Block editor or Classic editor should be used on specific post types, and you can change the editor by going to Toolset > Post Types and editing the post type in question (in this case, Pages).
So the first thing I would do is check that setting.
By default the editor is set to Block editor for all post types, so I'm a little surprised that it might be set to Classic editor for Pages without you having explicitly done that, but in any case that is the likely explanation.
