Is this appearing in the front end or is it just appearing in your server logs? Did the error message appear when you updated to v16.2 of Yoast SEO for WordPress? * Please also do check if you are on the latest version of WordPress 5.7.2, have the latest version of your other plugins and themes, and meet all of the necessary [plugin requirements](https://yoast.com/help/plugin-requirements/). * Thread Starter [Dan Stramer](https://wordpress.org/support/users/danstramer/) * (@danstramer) * [4 years, 11 months ago](https://wordpress.org/support/topic/warning-in_array-expects-parameter-2-to-be-an-array/#post-14453017) * Hi, It’s appearing in the backend.

And if not, when it reappears when you start enabling other plugins again. We believe this to be a plugin or theme conflict, as we can’t reproduce this with 16.3 free in a local environment where WP_DEBUG is set to true. * In order to test this, we encourage you to use the Health Check plugin troubleshooting mode, you can find the relevant steps to do this here: [https://yoast.com/help/how-to-check-for-plugin-conflicts/](https://yoast.com/help/how-to-check-for-plugin-conflicts/). * As a sidenote: we do see you have 3 must use plugins as well, which might filter or change the auto-updates specific options in your database. When every plugin but Yoast SEO is active and the warning does still persists, please temporary rename the mu-plugins directory in your WordPress installation and check if the warning still shows. If not, one of the 3 is interfering here. - This reply was modified 4 years, 11 months ago by [Jeroen Rotty](https://wordpress.org/support/users/jeroenrotty/).
