I understand the importance of validating configuration, but I have compelling reasons to avoid it. Is it possible to disable the configuration validator?

• You can disable the configuration validator by adding:

  define( 'WPCF7_VALIDATE_CONFIGURATION', false );

• to your wp-config.php, or adding:

  add_filter( 'wpcf7_validate_configuration', '__return_false' );

• to your theme’s functions.php.

解决：

进入插件所在目录： /home/wwwroot/xxx.com/wp-content/themes/Avada
编辑functions.php
加入：

add_filter( 'wpcf7_validate_configuration', '__return_false' );
