Object of class WP_Post could not be converted to int

Hello,

This seems to a theme issue because the error is pointing you on your themes functions.php, I would suggest checking the functions.php around line 249.

In my original message, I copied these lines from the functions.php file:

Here are Lines 248, 249, 250 from twenty twelve functions.php file:
// Add a page number if necessary.
if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() ) {
$title = “$title $sep ” . sprintf( __( ‘Page %s’, ‘twentytwelve’ ), max( $paged, $page ) );

Clearly the problem is there. The original error message points to line 249 specifically.

However, I don’t understand what change is needed.

Your functions.php is not the original anymore. The original lines 248-250 are this:

* @param string $mce_css CSS path to load in TinyMCE.
* @return string Filtered CSS path.
*/

The lines you are referring to are originally 292-294.

The original, complete function which contains the code you are referring to is:

function twentytwelve_wp_title( $title, $sep ) {
	global $paged, $page;

	if ( is_feed() )
		return $title;

	// Add the site name.
	$title .= get_bloginfo( 'name', 'display' );

	// Add the site description for the home/front page.
	$site_description = get_bloginfo( 'description', 'display' );
	if ( $site_description && ( is_home() || is_front_page() ) )
		$title = "$title $sep $site_description";

	// Add a page number if necessary.
	if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() )
		$title = "$title $sep " . sprintf( __( 'Page %s', 'twentytwelve' ), max( $paged, $page ) );

	return $title;
}
add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );

Please check if that is indeed your complete function as well.

Since the problem is the title, have you tried changing the title, update the post and check it again? ??

I downloaded a zip file of the twenty twelve theme. Then I replaced my website’s twenty twelve functions.php file with the downloaded (default) file. No change, same error still happens.

The Page in question is my Events Calendar Page
Events Manager Options:
Pages | Event List/Archives | Events page
I’ve selected a page named Club Events Calendar
That page was created back in February and its title has not been changed.

I will ask again:
did you change the title to test it?

Please change the tile, so that WordPress can recreate it.

I’ve just changed the page title. The error still happens.

I’ve just created a brand new Events page and assigned it in the Events Manager Pro settings (pulldown menu) as the Events page – Pages | Event List/Archives | Events page
I still have the same error when viewing this new Events page.

I’ve found a workaround to the problem. It’s only a workaround and not a true solution.
I’ve edited the twentytwelve theme functions.php file.
Remarked out three lines. These lines show as lines 249-251 when viewing functions.php in Visual Studio Code. This is in the // Add a page number if necessary section of functions.php.
// if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() ) {
// $title = “$title $sep ” . sprintf( __( ‘Page %s’, ‘twentytwelve’ ), max( $paged, $page ) );
// }
