Description

I'm getting following error after upgrading to WP 5.0.3:

Invalid argument supplied for foreach() in /wp-includes/blocks.php on line 183\n

As a result - output HTML is corrupted, some letters and words disappear in HTML resulting output.

Code statement which generating error:

<?php
foreach ( $block['innerContent'] as $chunk ) { $block_content .= is_string( $chunk ) ? $chunk : render_block( $block['innerBlocks'][ $index++ ] ); }

I'm using PHP 7.2.13 and MariaDB 10.3.8. Disabling all plugins and using default WP 5.0 theme - not helped at all.

I tested it on PHP 5.6.39 and PHP 7.1.25 - all works fine. Bug appears on PHP 7.2.13 only.

Thank you for the bug report, @filosofem!

Could you attach a copy of the raw post content to this ticket? A copy directly from the database would be preferable. If you're not sure how to do that, you can open it in the block editor, click the options menu on the top right of the editor screen, and select the "Code Editor" option.

Sure, raw post content looks as expected. Problem happens on outputting/rendering raw content into HTML:

<p>Today, more than 7 billion people live in the world. The first live richly and luxuriously, the second - representatives of the middle class, and still others live poorly. The distribution of wealth in the world is not in favor of the majority of the population. Almost all world resources belong to a small part of the inhabitants of the planet Earth. Is this a fair allocation of resources?</p>

<h2>The pyramid of the distribution of world wealth</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>According to the Global Wealth Report 2018 research report from the Swiss company Credit Suisse, world wealth is estimated at $317 trillion. This amount consists of tangible (real estate, cars and other valuable property) and financial (securities, deposits, retirement savings, etc.) assets less credits and debts. The number of adult working population in the world is 5 billion.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>The distribution of wealth in the world looks like a pyramid as follows:<br>

<h2>Conclusion</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>A person will fall into the top of the pyramid of wealth distribution in the world, becoming wealthy, if he sincerely wants it, making efforts and acting. Competition is not terrible, treat it as a challenge, a game and sport.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>To get into the group of millionaires with wealth from $1 to $5 million, becoming a citizen of an “elite country” is within everyone’s power. It is even easier to get into the "country" of representatives of the class above the average with a welfare from $100 thousand to $1 million. There are 436 million such people in the world, more than the population of the USA.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Moving toward these goals, rising from level to level of the pyramid of distribution of world wealth, should be resolutely and gradually, starting small. In any case, it will turn out to significantly improve the financial health and social status. History knows many examples when people chose out of poverty, becoming rich, or at least financially independent.</p>

<p>It's hard not to agree with this quote. Calculate at what level the pyramid of wealth distribution in the world is you. Are your property and savings estimated at least 10 thousand dollars?</p>

<!-- wp:paragraph -->
<p>You will have an interesting fascinating journey to the heights of the pyramid of the distribution of world wealth, if you are not afraid of competition and are ready to act to get rich and win your own place in the global hierarchy.</p>

@filosofem are you still experiencing this issue?

I have done some testing with 5.0.3 and 5.1 but I have been unable to reproduce. I tested on PHP 7.3 and 7.2.15.

Marking this a candidate for closure as worksforme, unless you are still experiencing this.

I'm going to close this out because I am not able to reproduce the issue and a lack of reporter feedback.

@filosofem if you are still experiencing this issue and can provide more details that others can use to reproduce, please do reopen.

This is caused by mbstring.func_overload PHP setting, see the upstream issue for more details.
