Did you restored from a backup? Or did a migration? Switched to another theme? * Thread Starter [DensitySK](https://wordpress.org/support/users/densitysk/) * (@densitysk) * [4 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-4043/#post-15211983) * correct. I do use Updraft Plus Backup plugin. Before every plugin update I always do a backup and if I notice anything strange, I always restore back until the problem has been solved. So there is definitely a restore from time to time. * Do you have a solution on how this can be solved? Or how can I completely remove your plugin from my website and all database entries, so I can cleanly re-install it again? * Plugin Author [jeffrey-wp](https://wordpress.org/support/users/jeffrey-wp/) * (@jeffrey-wp) * [4 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-4043/#post-15212414) * It is likely a problem with the serialized data. Sometimes this happens with imports from a backup or a (badly written) replace plugin for the database. It could be a wrong charset of the import file or a unsufficient max allowed file size. If you want to completely remove the plugin from the database the remove alle row in wp_postmeta with meta_key _backorder_max or _backorder_description. And in the wp_options table remove everything where the option_name starts with` wcbm_` (wcbm_backorder_report_order_statuses, wcbm_backorder_mail_notification, wcbm_show_available_items). * Thread Starter [DensitySK](https://wordpress.org/support/users/densitysk/) * (@densitysk) * [4 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-4043/#post-15229222) * thank you. I have removed the database rows and reinstalled the plugin. I will now wait for the next orders with backordered items and check if it shows any fatal errors. * Thread Starter [DensitySK](https://wordpress.org/support/users/densitysk/) * (@densitysk) * [4 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-4043/#post-15279385) * after checking, your plugin still shows fatal errors all over again. It has been purged from the website and database completely and still after installing it again now I start to see the same fatal errors again. * There were no database or backup restorations, migrations, or any kind of switch to a different theme. * ``` 2022-01-22T10:57:48+00:00 CRITICAL Uncaught TypeError: strpos(): Argument #1 ($haystack) must be of type string, array given in /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woo-backorder-manager-pro/woo-backorder-manager-pro.php:669 Stack trace: #0 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woo-backorder-manager-pro/woo-backorder-manager-pro.php(669): strpos(Array, '%available%') #1 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-includes/class-wp-hook.php(303): WooBackorderManagerPro->wcbm_get_availability_text('', Object(WC_Product_Variable)) #2 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-includes/plugin.php(189): WP_Hook->apply_filters('', Array) #3 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php(2082): apply_filters('woocommerce_get...', '', Object(WC_Product_Variable)) #4 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php(2058): WC_Product->get_availability_text() #5 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woocommerce/includes/wc-template-functions.php(3515): WC_Product->get_availability() #6 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/et-core-plugin/app/models/customizer/class-ajax-search.php(313): wc_get_stock_html(Object(WC_Product_Variable)) #7 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-includes/class-wp-hook.php(303): Etheme_ajax_search->search_results('') #8 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters('', Array) #9 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-includes/plugin.php(470): WP_Hook->do_action(Array) #10 /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-admin/admin-ajax.php(202): do_action('wp_ajax_nopriv_...') #11 {main} thrown in /data/f/c/fc2fe6bd-5916-44b4-b9c0-13c5319e4e79/XXXXX/web/wp-content/plugins/woo-backorder-manager-pro/woo-backorder-manager-pro.php on line 669 ``` Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘fatal error’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/woo-backorder-manager_8f8f8f.svg) * [WooCommerce Backorder Manager](https://wordpress.org/plugins/woo-backorder-manager/) * [Support Threads](https://wordpress.org/support/plugin/woo-backorder-manager/) * [Active Topics](https://wordpress.org/support/plugin/woo-backorder-manager/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/woo-backorder-manager/unresolved/) * [Reviews](https://wordpress.org/support/plugin/woo-backorder-manager/reviews/) * 5 replies * 2 participants * Last reply from: [DensitySK](https://wordpress.org/support/users/densitysk/) * Last activity: [4 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-4043/#post-15279385) * Status: resolved
