If you are getting this error ‘Warning: count(): Parameter must be an array or an object that implements Countable in’ /wp-includes/post-template.php on line 310 on top of your homepage then it can be due to PHP version or upgrade issue.
First of all relax this error is a warning or notice about some bug in the code of a particular file not a fatal error or internal server error which can stop your website from loading.
Let’s fix this WordPress error, so the code at this line looks like this
if ( $elements[‘page’] > count( $elements[‘pages’] ) ) {
$elements[‘page’] = count( $elements[‘pages’] );
}
Add this line is_array( $elements[‘pages’] ) && count( $elements[‘pages’] )
New code looks like this
if ( $elements[‘page’] > ( is_array( $elements[‘pages’] ) && count( $elements[‘pages’] ))) {
$elements[‘page’] = count( $elements[‘pages’] );
}
Replace the old line of code with the new one mentioned above and save the php file.
Now check your website if the issue is resolved.
