When you look at the exports listed on the “Manage Exports” page, is the “Query” column empty for any of them? * Thread Starter [gatespace](https://wordpress.org/support/users/gatespace/) * (@gatespace) * [2 years, 10 months ago](https://wordpress.org/support/topic/php-8-1-uncaught-typeerror/#post-16937786) * Thanks for the reply. * I had stopped the plugin on the server. When I activate the plugin to view the comments, I get the above error and cannot access the WordPress dashboard. * ```wp-block-code [01-Aug-2023 08:40:36 UTC] PHP Fatal error:  Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array, null given in /var/www/vhosts/example.com/wp-content/plugins/wp-all-export/src/App/Service/Addons/AddonService.php:50 ``` * Thread Starter [gatespace](https://wordpress.org/support/users/gatespace/) * (@gatespace) * [2 years, 10 months ago](https://wordpress.org/support/topic/php-8-1-uncaught-typeerror/#post-16938239) * Additional Comments. I found a few records in php7.4 environment where the “Query” column is “Broken: please delete”. * Plugin Author [WP All Import](https://wordpress.org/support/users/wpallimport/) * (@wpallimport) * [2 years, 10 months ago](https://wordpress.org/support/topic/php-8-1-uncaught-typeerror/#post-16939886) * Hey [@gatespace](https://wordpress.org/support/users/gatespace/), * Okay, if it’s possible to change the site to PHP 7.4 temporarily, I would advise doing so & then removing any exports where “Broken: please delete” appears in the “Query” column. Once that’s done, you can switch it back to PHP 8.1. * Thread Starter [gatespace](https://wordpress.org/support/users/gatespace/) * (@gatespace) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-8-1-uncaught-typeerror/#post-16943017) * The server on which the plugin is installed is a shared server and cannot be downgraded to PHP 7.4. * Also, manual deletion is time consuming due to the large number of records. * I would like the Fatal error in the plugin to be resolved. * Plugin Author [WP All Import](https://wordpress.org/support/users/wpallimport/) * (@wpallimport) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-8-1-uncaught-typeerror/#post-16966902) * Hey [@gatespace](https://wordpress.org/support/users/gatespace/), * Thank you for your patience here. * In this case, we’d need to have more information to help resolve this for you.

I will describe the steps to reproduce the problem as a reference for other users. * 1. create a custom post type (test_post_type) and create a post 2. export post type (test_post_type) data with WP All export3. delete the post type (test_post_type) 4. in PHP7.4 the “Query” column with “Broken: please delete” is causing the error. Uncaught TypeError in PHP 8.1 if this record remains.
