Description
Warning: count(): Parameter must be an array or an object that implements Countable in wp-includes/meta.php on line 210
This error prevents any posts from being updated. It seems it is erroring because $old_value may not always be an array.
This is the original line that causes errors:
if ( count( $old_value ) == 1 ) {
The fix checks to see if $old_value is an object or array:
if ( (is_array($old_value) || is_object($old_value)) && count( $old_value ) == 1 ) {
After fix is implemented, everything seems to work fine.

We could use the is_countable() polyfill added in #43583.

I think is_countable() function added in PHP 7.3 . How to deal with the previous version?

is_countable works best and takes care of the two codes. Appreciate the update! Hopefully see it in the core! Every time WordPress gets an update, i have to add this code in there for PHP 7.3.

Hey @mattgates
is_countable is available in WP core from 4.9.6 https://developer.wordpress.org/reference/since/4.9.6/ but my point was that if you using any PHP lower version i.e. 7.2 or 5.6 then you will get Fatal error
