 * We have The Events Calendar and the Yoast free SEO plugin installed on our staging
   site and we are receiving the following PHP error:
 * **Warning**: array_key_exists(): The first argument should be either a string
   or an integer in **/home/customer/www/staging2.atlanticshoresliving.com/public_html/
   wp-content/plugins/wordpress-seo/src/context/meta-tags-context.php** on line **
   563**
 * If we deactivate Yoast the error goes away.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fyoast-php-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi [@ermack](https://wordpress.org/support/users/ermack/)
 * Thanks for reaching out.
 * It seems that the warning message you received is related to the Yoast plugin
   and not The Events Calendar. Have you tried contacting the Yoast team for help
   with this specific issue?
 * Let me know if you have further questions or concerns.
