 * Hello [@richard1250](https://wordpress.org/support/users/richard1250/)
 * Thank you for the support topic, When you mean “There are many URL errors in 
   red” did you mean that there are many validation errors on your Site?

 * Yes, that’s correct. It says validated urls 11 in red and also error index 13
   in red. Have no idea what to do.

 * Hello [@richard1250](https://wordpress.org/support/users/richard1250/)
 * Thank you for confirming, As we checked your site you are currently using Sandboxing
   with Loose Mode, If one of plugin or your theme is incompatible with AMP it will
   generate into validation errors.( those red ones)
 * The Sandboxing Mode with Loose Mode will allows any invalidations (it will retain
   those validation errors) that are required for functionalities of your site. 
   eg: javascript required to run slideshow, which will be retained on Sandboxing
   Mode
 * The focus of using Sandboxing is improve Page Experience (Which is considered
   a [new factor when ranking sites](https://developers.google.com/search/docs/advanced/experience/page-experience))
   by using bento components where ever AMP plugin seeks opportunity to use [bento component](https://bentojs.dev/)
   it will replace the slow performing element with bento components
 * eg: You have youtube embed on your page which take much to time to load, AMP 
   plugin will replace it with [bento component](https://bentojs.dev/components/bento-youtube/)
   and improve it’s loading speed resulting in good page experience.
 * Regarding those errors those are just to inform you that there are some invalidations
   which can be removed to achieve Strict AMP. If you are sticking to Sandboxing
   Mode you can ignore them.
 * You can learn more about Sandboxing Mode in [our documentation ](https://amp-wp.org/documentation/getting-started/settings-screen/sandboxing-experimental/)
 * Let me know if you have further questions.
