* I’m trying out the plugin “Gutenberg Blocks – PublishPress Blocks Gutenberg Editor
Plugin” and when I view any Page in my WordPress site (specifically a site within
a multi-site), I get the following errors:
* ```wp-block-code
Warning: count(): Parameter must be an array or an object that implements Countable in /PATH/TO/wp-includes/post-template.php on line 321
Notice: Trying to access array offset on value of type null in /PATH/TO/wp-includes/post-template.php on line 327
```
* Any suggestions?

* Hi [@billb101](https://wordpress.org/support/users/billb101/)
* Thanks for using PublishPress Blocks.
* Just to confirm, the issue disappear if you deactivate PubilshPress Blocks?

* Yes, it only shows up when I have the plugin installed. It appears that the array
element
* ```wp-block-code
$elements['pages']
```
* is null and that is generating the error in both cases I think. To determine
this, with the plugin installed and activated I made the following changes to
* ```wp-block-code
wp-includes/post-template.php
```
* First off I added a print_r statement above line 321, i.e., I changed
* ```wp-block-code
if ( $elements['page'] > count( $elements['pages'] ) ) {
// Give them the highest numbered page that DOES exist.
$elements['page'] = count( $elements['pages'] );
}
```
* to
* ```wp-block-code
echo ''.print_r($elements, true).'
';
if ( $elements['page'] > count( $elements['pages'] ) ) {
// Give them the highest numbered page that DOES exist.
$elements['page'] = count( $elements['pages'] );
}
```
* and got the following output
* ```wp-block-code
Array
(
[page] =>
[more] => 1
[preview] =>
[pages] =>
[multipage] =>
)
```
* And for the other error I added a print_r above line 327, i.e., I changed
* ```wp-block-code
$content = $elements['pages'][ $page_no - 1 ];
```
* to
* ```wp-block-code
echo ''.print_r($elements, true).'
';
$content = $elements['pages'][ $page_no - 1 ];
```
* and got the following output
* ```wp-block-code
Array
(
[page] =>
[more] => 1
[preview] =>
[pages] =>
[multipage] =>
)
```
* My WordPress multisite works fine otherwise and does not generate these errors
unless I install and activate the aforementioned plugin. Thank you for your help!

* Thanks [@billb101](https://wordpress.org/support/users/billb101/) !
* I’m not able to reproduce the issue. To check if the theme is somehow involved
too, may you keep PublishPress Blocks active, and use a different theme like
Twenty Twenty-One for a minute and see if the issue is gone?
* Looking forward to help you

* [@rizaardiyanto](https://wordpress.org/support/users/rizaardiyanto/) Sorry for
not responding sooner. I did try a the Theme Twenty Twenty-One and the problem
disappeared. The problem happens with my Theme which is a custom Theme I wrote
that uses ACF Pro and Timber. This is the first time I’ve had a problem with
a plugin due to my Theme. Suggestions?

* [@billb101](https://wordpress.org/support/users/billb101/) We will not be able
to give relevant suggestions without doing proper troubleshooting.
* Unfortunately, as the issues related custom theme, we will not be able to do
troubleshoot there.
* We suggest you to check with dedicated developer in case there is something wrong
with the custom theme.
* Thanks,
