 Hi there,

 I hope this email finds you well. Unfortunately, we've recently
 encountered a critical error that requires immediate attention. This issue
 pertains to the single page templates, specifically an example like this:
 https://volunteeringqld.org.au/governance/before-you-join/. The error was
 not present a week ago, and we're currently grappling to determine its
 cause. This problem was initially observed on both WP6.22 and WP6.3.

 The post https://volunteeringqld.org.au/governance/before-you-join/
 conncted to a singletemplate php mytemplate/single-governance-before-you-
 join.php, what calls <?php the_content() ?> what throws error "There has
 been a critical error in this website" and output steam finishes. Log
 error gives this line:
 "PHP message: PHP Fatal error: Uncaught TypeError: Unsupported operand
 types: WP_Post - int in /home/vqadmin/public_html/wp-includes/post-
 template.php:330Stack trace:#0 /home/vqadmin/public_html/wp-includes/post-
 template.php(247): get_the_content()#1 /home/vqadmin/public_html/wp-
 content/themes/volunteeringAU/single-governance-before-you-join.php(411):
 the_content()#2 /home/vqadmin/public_html/wp-includes/template-
 loader.php(106): include('...')#3 /home/vqadmin/public_html/wp-blog-
 header.php(19): require_once('...')#4
 /home/vqadmin/public_html/index.php(17): require('...')#5 {main} thrown in
 /home/vqadmin/public_html/wp-includes/post-template.php on line 330',
 referer: https://volunteeringqld.org.au/governance/"

 To address this, we have applied the following code snippet in post-
 template.php line 330:
         if( ! is_int($page_no)) {
                 $page_no = 1; // Igor
                 //echo '<!--'.print_r( $elements, true ). '-->';
         }

 When echo ancommented it gives
 Array
 (
     [page] => WP_Post Object
         (
             [ID] => 5
             [post_author] => 7

             [post_date_gmt] => 2021-10-21 04:24:08
             [post_content] =>
             [post_title] => Home
             [post_excerpt] =>
             [post_status] => publish
             [comment_status] => closed
             [ping_status] => closed
             [post_password] =>
             [post_name] => home
             [to_ping] =>
             [pinged] =>
             [post_modified] => 2023-05-26 13:50:03
             [post_modified_gmt] => 2023-05-26 03:50:03
             [post_content_filtered] =>
             [post_parent] => 0
             [guid] => https://volunteeringqld.org.au/?page_id=5
             [menu_order] => 0
             [post_type] => page
             [post_mime_type] =>
             [comment_count] => 0
             [filter] => raw
         )

     [more] => 1
     [preview] =>
     [pages] => Array
         (
             [0] => <!-- wp:paragraph -->
 <p><strong>Achieving a good transition to the next volunteer who will take
 over from you has benefits for you, the organisation, and the incoming
 governance member. Let’s explore things you can do to ensure a good
 handover.</strong></p>
 <!-- /wp:paragraph -->

 <!-- wp:paragraph -->
 <p>In this stage of your Governance journey we explore:</p>
 <!-- /wp:paragraph -->
         )

     [multipage] => 0
 )

 As you can see, instead of having 1 in $elements['page'], it contains a
 WP_Post object of the very first post from the database, even not the one
 that is displayed.

 We are hopeful that this information helps you in resolving the issue and
 that a solution will be included in an upcoming patch. Please don't
 hesitate to reach out if you require more details or assistance.

 Best regards,
 Igor
