Can someone explain how to fix this? WP error message follows. Website replaced with #####. * WordPress version 5.6 Current plugin: WooCommerce Admin (version 1.9.0) PHP version 7.4.14 * Error Details ============= An error of type E_ERROR was caused in line 64 of the file /home/#####/public_html/wp-content/plugins/woocommerce-admin/src/Features/ Features.php.

Does this error happen if you are using a default WordPress theme and only have WooCommerce and WooCommerce Admin active? * If the problem still occurs in the above test, can you provide us with a copy of the site’s System Status Report so we can take a look? * Thanks! * Thread Starter [Dave](https://wordpress.org/support/users/dave2055/) * (@dave2055) * [5 years, 5 months ago](https://wordpress.org/support/topic/woocommerce-admin-critical-error/#post-13998777) * Shaun, here is the WP System Status Report. All plug-ins are up-to-date and there are no inactive plugins. * ``` ### wp-core ### version: 5.6 site_language: en_US user_language: en_US timezone: -05:00 permalink: /%category%/%postname%/ https_status: true multisite: false user_registration: 0 blog_public: 1 default_comment_status: closed environment_type: production user_count: 1 dotorg_communication: true ### wp-paths-sizes ### wordpress_path: /home/vitaakrb/public_html wordpress_size: 2.68 GB (2872491903 bytes) uploads_path: /home/vitaakrb/public_html/wp-content/uploads uploads_size: 511.09 MB (535915798 bytes) themes_path: /home/vitaakrb/public_html/wp-content/themes themes_size: 38.62 MB (40497337 bytes) plugins_path: /home/vitaakrb/public_html/wp-content/plugins plugins_size: 156.41 MB (164003356 bytes) database_size: 18.16 MB (19039822 bytes) total_size: 3.38 GB (3631948216 bytes) ### wp-active-theme ### name: NaturaLife (naturalife) version: 1.9.5 author: RT-Themes author_website: http://themeforest.net/user/stmcan parent_theme: none theme_features: core-block-patterns, post-thumbnails, header-footer-elementor, menus, automatic-feed-links, title-tag, woocommerce, customize-selective-refresh-widgets, gutenberg, widgets, editor-style theme_path: /home/vitaakrb/public_html/wp-content/themes/naturalife auto_update: Disabled ### wp-themes-inactive (5) ### Product: version: 1.0, author: Suavethemes, Auto-updates disabled Twenty Nineteen: version: 1.9, author: the WordPress team, Auto-updates disabled Twenty Seventeen: version: 2.5, author: the WordPress team, Auto-updates disabled Twenty Sixteen: version: 2.3, author: the WordPress team, Auto-updates disabled Twenty Twenty: version: 1.6, author: the WordPress team, Auto-updates disabled ### wp-plugins-active (22) ### Akismet Anti-Spam: version: 4.1.8, author: Automattic, Auto-updates enabled Auto Image Attributes From Filename With Bulk Updater: version: 1.6, author: Arun Basil Lal, Auto-updates enabled Autoptimize: version: 2.8.1, author: Frank Goossens (futtta), Auto-updates enabled Classic Editor: version: 1.6, author: WordPress Contributors, Auto-updates enabled Contact Form 7: version: 5.3.2, author: Takayuki Miyoshi, Auto-updates enabled Duplicate Page: version: 4.3, author: mndpsingh287, Auto-updates enabled Elementor: version: 3.1.1, author: Elementor.com, Auto-updates enabled Envato Market: version: 2.0.6, author: Envato, Auto-updates enabled Insert Headers and Footers: version: 1.5.0, author: WPBeginner, Auto-updates enabled Loginizer: version: 1.6.6, author: Softaculous, Auto-updates enabled NaturaLife | Extensions Plugin: version: 1.9.3, author: RT-Themes, Auto-updates enabled PageLayer: version: 1.4.5, author: Pagelayer Team, Auto-updates enabled ShortPixel Image Optimizer: version: 4.21.1, author: ShortPixel, Auto-updates enabled Slider Revolution: version: 6.3.6, author: ThemePunch, Auto-updates enabled UpdraftPlus -

The error on your site appears to be related to the new “Navigation” feature that is part of the WooCommerce Admin plugin. Can you go to the **WooCommerce > Settings > Advanced** page and let me know if that option is currently enabled or not? Thanks! * Thread Starter [Dave](https://wordpress.org/support/users/dave2055/) * (@dave2055) * [5 years, 5 months ago](https://wordpress.org/support/topic/woocommerce-admin-critical-error/#post-13999293) * Shaun, Unfortunately, I cannot access WooCommerce at all. If I attempt to access anything for WooCommerce, such as go to Settings, the page is blank except for this error message: * There has been a critical error on this website. Please check your site admin email inbox for instructions. * Then, I receive an email with the error message I previously uploaded here. - This reply was modified 5 years, 5 months ago by [Dave](https://wordpress.org/support/users/dave2055/). - This reply was modified 5 years, 5 months ago by [Dave](https://wordpress.org/support/users/dave2055/). - This reply was modified 5 years, 5 months ago by [Dave](https://wordpress.org/support/users/dave2055/). * Thread Starter [Dave](https://wordpress.org/support/users/dave2055/) * (@dave2055) * [5 years, 5 months ago](https://wordpress.org/support/topic/woocommerce-admin-critical-error/#post-14002860) * Hi Shaun, * Looking forward to your reply and figuring out how to correct the WooCommerce error.

In Settings – Advanced – Page Setup what is it you wanted me to check? You previously said, “let me know if that option is currently enabled” What option? Navigation? If so, there is no Navigation setting on that page. * When I do find that option, should it be enabled or disabled? * The headings are Page Setup, Checkout Endpoints, Account Endpoints. * Plugin Support [Shaun Kuschel a11n](https://wordpress.org/support/users/shaunkuschel/) * (@shaunkuschel) * Automattic Happiness Engineer * [5 years, 5 months ago](https://wordpress.org/support/topic/woocommerce-admin-critical-error/#post-14010671) * Hey [@dave2055](https://wordpress.org/support/users/dave2055/), * The “Navigation” feature that I referenced on the “Advanced” settings page is a beta option that was added by the WooCommerce Admin plugin. Now that the plugin is deactivated, it shouldn’t show as an option anymore. * To further clarify, [WooCommerce Admin is what we refer to as a ‘feature plugin’](https://woocommerce.com/posts/woocommerce-admin-a-new-central-dashboard-for-woocommerce/) that allows us to add, test, and get feedback in advance for new features that we’d like to include in future updates to core WooCommerce. * The ‘simple’ resolution for that error is to disable WooCommerce Admin, but we’d definitely be interested in digging into the actual cause of the problem. However, since I haven’t been able to reproduce the problem, that is why I assume there is a conflict with something else on the site/environment. * The best way to confirm if there is a code conflict would be to temporarily switch to a default WordPress theme and deactivate all plugins except WooCommerce and WooCommerce Admin and see if the issue still occurs (preferably on a staging copy of the site). If not, slow re-activate plugins and re-test until the problem occurs again. * [Missy a11n](https://wordpress.org/support/users/m155y5/) * (@m155y5) * Automattic Happiness Engineer * [5 years, 5 months ago](https://wordpress.org/support/topic/woocommerce-admin-critical-error/#post-14043846) * We haven’t heard back from you in a while, so I’m going to go ahead and mark this thread as resolved.
