 * Hello [@hnkgo1](https://wordpress.org/support/users/hnkgo1/)
 * Thank you for supporting the topic, As we checked your site it seems to be using
   experimental Sandboxing with Loose Mode which means you are opted-in to keep 
   all AMP invalidations (the errors you saw) so that your site can function properly
   while benefiting from AMP components to improve your site’s page experience.
 * What you can do?
    1) If your focus is getting a good page experience instead 
   of AMP you simply just ignore all errors.
 * 2) If want AMP benefits, then I will recommend contacting respective plugin support
   asking them for AMP support, you can always [find alternatives](https://amp-wp.org/ecosystem/)
   for those plugins from AMP Compatible plugin listing page.([screenshot](https://prnt.sc/25fx54e))
 * Alternatively, you may find AMP compatibility [mini plugin/extensions](https://amp-wp.org/documentation/extending-amp-compatibility-extensions-and-mini-plugins/)
   for some popular plugins like Contact Form 7
 * JFI: You have two cache plugins installed and active ie, Lightspeed and WP Super
   cache, it will be a good idea to choose only one.
 * Hope this helps
