    Hello! We have our WooCommerce WordPress site hosted by Ionos. Today, out of nowhere, the site became inaccessible and stated “There Has Been a Critical Error on This Website”.

    I contacted Ionos support via live chat and they were able to deactivate the Zettle POS plugin, which they said is what was causing the critical error on my website. Here is the plugin fatal error Ionos provided me:

    wp plugin activate zettle-pos-integration
    Fatal error: Declaration of Inpsyde\Wp\HttpClient\Client::sendRequest(Psr\Http\Message\RequestInterface $request): Psr\Http\Message\ResponseInterface must be compatible with Psr\Http\Client\ClientInterface::sendRequest(Automattic\WooCommerce\GoogleListingsAndAds\Vendor\Psr\Http\Message\RequestInterface $request): Automattic\WooCommerce\GoogleListingsAndAds\Vendor\Psr\Http\Message\ResponseInterface in /homepages/36/d4297208015/htdocs/wordpress/wp-content/plugins/zettle-pos-integration/vendor/inpsyde/psr-18-wp-http-client/src/Client.php on line 77

    Ionos indicated that this is an error in running a wpcli command in activating a plugin. It appears there are compatibility issues with the plugin or themes or version of WordPress. Ask them if there are any other requirements they need to make sure the plugin works for our site.

    Any help with this would be greatly appreciated!

    Hello @mattphillips

    Thank you for reaching out to us, we are here to help.

    I discussed this with our lead developer, and we believe this is a conflict with another plugin (WC Google Listings & Ads) and is caused because it loads a different version of the same library or actually maybe not version.

    It seems like this plugin tried to prefix its libraries to avoid such conflicts, but they did it only for part of the PSR HTTP-related interfaces, making it worse when they use each the other one. This is why this issue should most likely be report to WooCommerce Google Listings & Ads.
    Also, you should probably check what version you are using of this plugin. If you are using the latest version, then downgrading to 2.4.7 should help for now. Here is the link to this site: https://ww.wp.xz.cn/plugins/google-listings-and-ads/#developers

    Let me know if this helped you resolve the issue for now.

    Kind regards,
    Joost
