Deprecated: Required parameter $field_id follows optional parameter $type

  • Hello,

    After updating all plugins and wordPress core at my website, I updated PHP to 8.0 and on most (maybe all?) admin pages now I see this PHP message

    “Deprecated: Required parameter $field_id follows optional parameter $type in /<home folder here>/public_html/penny.eliza.pro/wp-content/plugins/arconix-faq/includes/metabox/includes/rest-api/CMB2_REST.php on line 698”

    This PHP message is followed by three more PHP messages that start like this:

    Warning: Cannot modify header information – headers already sent by (output started a

    I see this error at the development website, where I’m displaying errors. The FAQ page still works there, so it’s PROBABLY OK for me to apply the PHP version change to the live website too. But I take such error messages as a sign of something WILL break in a future update. Can you see about fixing this error and let me know?

    Thanks in advance,
