    I’m getting various white screens after upgarding to php 8.0.16 most notably on site health page and amp settings.

    Here’s the amp settings error:
    /wp-admin/admin.php?page=amp-options
    /wp-admin/site-health.php (identical error on both)
    WordPress 5.9.1
    Theme: Newspaper (11.4.1)
    Current plugin: AMP (2.2.1)
    PHP 8.0.16

    Error type E_ERROR was caused in line 548 of the file /var/www/vhosts/[siteurl]/httpdocs/wp-content/plugins/amp/src/Admin/SiteHealth.php. Error message: Uncaught TypeError: preg_match(): Argument #2 ($subject) must be of type string, array given in /var/www/vhosts/.../httpdocs/wp-content/plugins/amp/src/Admin/SiteHealth.php:548

    Nope, error on actual articles now. None of the amp posts work.

    Failed to prepare AMP page

    A PHP error occurred while trying to prepare the AMP response. This may not be caused by the AMP plugin but by some other active plugin or the current theme. You will need to review the error details to determine the source of the error.

If you get stuck, you may want to share any details in a new topic on the plugin's support forum.

The exact details of the error are hidden for security reasons. To learn more about this error, enable the WordPress debugging display (by setting both WP_DEBUG and WP_DEBUG_DISPLAY to true), or look into the PHP error log. Learn more about Debugging in WordPress.

    That’s a strange one: Couldn't fetch AmpProject\Dom\Element. I’ve never seen that before.
