[1.5.7.] first subpage not displayed

I have the same symptoms as described by @reckus 🙁

It happens with the classic editor in my articles that I imported from MPP version 1.3.7 where this feature worked.

But it also happens on a fresh installation like the one in this example:

No text before first shortcode / but on subpage 2… (admin view)

With text before the first shortcode / (admin view)

It is not possible to change the default title as in previous versions.

The language files are inside the plugin and intact. I installed the site and MPP in Spanish and later changed the site setting to default English (en_US). To test, I deleted the es_ES translations that WP gets automatically. I reset the site language to es_ES which forced to download the new spanish language files from the repository but everything is still the same. It seems that the language settings in the user profile do not influence this.

So, neither English nor Spanish texts are displayed. However, on my production site this does not happen, although it might work because of existing legacy files from previous versions.

I don’t quite understand.

Well, it must be a one-off. Let’s let it go.

Regarding the above updates, I’m sorry to say that they don’t seem to work on my staging site.

What happens is that the empty page is generated when I try to customize the first title. That is, starting the post with a shotcode. It happens both in classic editor and with blocks, in pre-existing content and new posts. I’m still testing to isolate the bug. Any ideas on what to check?

Sorry, it doesn’t seem to be that serious. I wasn’t using the appropriate MPP version.

Environment: legacy content from MPP 1.3 versions.WP 5.6.1+ MPP 1.5.11. With Classic Editor plugin 1.6: settings Default editor for all users – Classic editor / Allow users to switch editor – Yes (these two settings seem to be irrelevant).

Whether in pre-existing classic content or a new post created with the classic editor, starting with a shortcode generates a first page (‘domain.com/page/’) without the subsequent text and without table of contents. If we access the url of successor subpages (‘domain.com/page/2/, 3/, 4/, …’) we will see the text attached to the previous shortcode (subpage) and not the text that would correspond. It scrolls through all the pages and creates an additional page.

Code:

[nextpage title="Custom subpage title"]00_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

[nextpage title="Section 1"]01_ Lorem ipsum dolor sit amet, consectetur adipiscing elit. 

[nextpage title="Section 2"]02_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Generated output: page 1

(empty)

Generated output: page 2

Section 1
00_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Generated output: page 3

Section 2
01_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Generated output: page 3 (or show all subpages)

Section 3
02_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

(…)

However, it seems to work if we start our post in the classic editor by inserting the comment markup generated by the block editor, using the code editor view.

Code that makes it work when using the classic editor:

<!-- wp:multipage/subpage {"title":"Custom subpage title"} -->
[nextpage title="Custom subpage title"]
<!-- /wp:multipage/subpage -->
00_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.

[nextpage title="Section 1"]01_ Lorem ipsum dolor sit amet, consectetur adipiscing elit. 

[nextpage title="Section 2"]02_ Lorem ipsum dolor sit amet, consectetur adipiscing elit.
