You can learn more about updating here: [https://yoast.com/help/how-can-i-update-my-free-plugin/](https://yoast.com/help/how-can-i-update-my-free-plugin/) * Also, can you confirm you are using WordPress 6.0.1? You can check by clicking on the W in the top left and selecting About. If you need to update, please check with your host provider. Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast. This guide explains more: [https://yoast.com/why-we-dont-support-old-wordpress-versions/](https://yoast.com/why-we-dont-support-old-wordpress-versions/) * If you update to the most current version of WordPress and Yoast SEO, does this resolve the issue? * If you have already confirmed that both Yoast SEO and WordPress are up to date and the issue is still occurring, we would next recommend performing a conflict check to determine whether another plugin or theme is interfering with the Yoast plugin. * The fastest way to do this is to **deactivate all non-Yoast plugins and switch to a standard theme** like [TwentyTwentyOne](https://wordpress.org/themes/twentytwentyone/). * Test this on your development or staging site, if you have one. If not, we recommend using the [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/) plugin. This plugin allows you to run a conflict check **without affecting normal visitors to your site**. * If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: [How to check for plugin conflicts](https://yoast.com/help/how-to-check-for-plugin-conflicts/). * Thread Starter [HMCurator](https://wordpress.org/support/users/hmcurator/) * (@hmcurator) * [3 years, 9 months ago](https://wordpress.org/support/topic/errors-when-exporting-settings/#post-15912319) * I have updated to 19.5.1 and was already running WP 6.0.1 and the problem persists. As it is a production site, I installed the health check plugin and set to troubleshooting mode and only activated Yoast SEO and the errors still happened. What is weird is I have two other production sites running Yoast with the same theme and several of the same plugins and I am not getting the error on them… * -Jon * Thread Starter [HMCurator](https://wordpress.org/support/users/hmcurator/) * (@hmcurator) * [3 years, 9 months ago](https://wordpress.org/support/topic/errors-when-exporting-settings/#post-15912330) * And I figured it out. The site giving me problems I had been trying PHP 8.0.22 whereas the other two were running 7.4 I set the version back to 7.4.30 and the errors went away. Please try exporting using PHP 8.0.22 and see if you get the errors. * -Jon * Plugin Support [Michael Tiña](https://wordpress.org/support/users/mikes41720/) * (@mikes41720) * [3 years, 8 months ago](https://wordpress.org/support/topic/errors-when-exporting-settings/#post-15982539) * Hi [@hmcurator](https://wordpress.org/support/users/hmcurator/) * Thanks for reporting this issue! * I tried this on a local site using PHP 8.0 and was able to reproduce the warning( Warning: Undefined array key 0 in /home/customer/www/mywebsite.com/public_html/ wp-content/plugins/wordpress-seo/admin/class-export.php on line 128) when trying to export the Yoast SEO settings. * I’ve created an issue in our internal repository for our developers to check on, so we can try and improve the compatibility with PHP 8.0 and newer. * [Jeroen Rotty](https://wordpress.org/support/users/jeroenrotty/) * (@jeroenrotty) * [3 years, 8 months ago](https://wordpress.org/support/topic/errors-when-exporting-settings/#post-16004259) * This thread was marked resolved due to a lack of activity, but you’re always welcome to re-open the topic.
