Warning: count(): Parameter must be an array or an object that implements Countable in /wp-includes/post-template.php on line 284
I met with this problem after installing The7 theme, while searching a bit I found that some people are facing this problem due to Jetpack plugin when reviewing the code I realize that this might be because of plugin or theme conflict with PHP version.
Solution:
Many people solved this problem by downgrading PHP version, but this could not be a good solution, I solved this problem by replacing this code at line 284-285 at wp-includes/post-template.php
if ( $page > count( $pages ) ) // if the requested page doesn't exist
$page = count( $pages ); // give them the highest numbered page that DOES exist
with this code
if ( is_array( $pages ) ) {
if ( $page > count( $pages ) ) // if the requested page doesn't exist
$page = count( $pages ); // give them the highest numbered page that DOES exist
} else {
$page = 0;
}

So what happens when WordPress updates? Isn’t that a CORE file you are editing and will be replaced by an update?
Thanks for sharing !
Nice snippet, the best fix I found after half an hour reading some odd workarounds here and there.
I was not sure what was the problem related to, but now this warning message makes sense.
Therefore, the warning is saying : “Parameter must be an array or an object”
So for a better testing of your $pages variable, the first line should be :
if ( is_array( $pages ) || is_object( $pages ) ) {
great, thanks for sharing this code
Thanks a lot, we’ll keep improving.
