 * Hello [@prayag922](https://wordpress.org/support/users/prayag922/)
 * Thank you for contacting us, There are multiple reasons why site scan might fail
   including third-party theme or plugin conflicts or cache plugins that add comment
   in JSON response.
 * After checking your site we found out that You are using Lite speed cache.
 * **LiteSpeed cache** might be the reason your site scan is failing it may have
   been conflicting with the AMP site scan.
 * Can you please add the following code snippet to your active theme’s functions.
   php file or in the custom plugin and check if that works for you?
 * `add_filter( 'litespeed_comment', '__return_false' );`
 * Additionally, To narrow down further, could you use the [Health Check & Troubleshooting plugin](https://wordpress.org/plugins/health-check/)
   and enable [its troubleshooting mode](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/#troubleshooting).
 * This mode disables active plugins and switches to a default theme safely since
   it only affects the experience of the logged-in user.
    - Please [enable the AMP plugin](https://jmp.sh/Zc5YLI9) and let me know if 
      the issue is present.
    - Enabling plugins and your theme one by one in this mode may help pinpoint 
      if something else is involved.
    - Note you can [disable troubleshooting mode](https://jmp.sh/uErQi8t) from the
      plugins page.
 * We hope this helps!

 * Hello [@prayag922](https://wordpress.org/support/users/prayag922/)
 * As we rechecked your site, we found that you are using two Cache and Optimisation
   plugins WP-Optimize Premium – Clean, Compress, Cache, and LiteSpeed Cache, We
   will recommend keeping only one active (Lite Speed Cache) they might have affected
   the initial server response time.
 * Additionally, Check why your Web Stories images size are not being correctly 
   shown, or contact [Web Stories support](https://wordpress.org/support/plugin/web-stories/)
   for the same 
   We hope this helps!

 * Sir, Coming back again on this topic, I removed another Cache Optimization plugins
   WP-Optimize Premium.
   (1) My query is why Plugin AMP shows incompatibility shown
   with Lite speed, Rank math, Astra Pro etc: [https://pastace.com/wp-content/uploads/2023/03/AMP_Check.png](https://pastace.com/wp-content/uploads/2023/03/AMP_Check.png)?(
   2) Second query is: In AMP mode Website performance is not good, How to resolve?
   Here is test result page: [https://pastace.com/wp-content/uploads/2023/03/Test_Non-AMP-Mode.png](https://pastace.com/wp-content/uploads/2023/03/Test_Non-AMP-Mode.png)
   and [https://pastace.com/wp-content/uploads/2023/03/Test-in-AMP-mode.png](https://pastace.com/wp-content/uploads/2023/03/Test-in-AMP-mode.png)

 * Hello [@prayag922](https://wordpress.org/support/users/prayag922/)
 * AMP is a web Component framework that uses a very strict set of rules, to ensure
   good performance AMP pages must follow those rules, those rules are defined by
   AMP validations
 * You can learn more about AMP validations in [AMP documentations](https://amp.dev/documentation/guides-and-tutorials/websites/learn/validation-workflow/validate_amp)
 * Plugins such as Astra Pro, Rank Math (Recent Updates in Rank Math) , and Lite
   Speed are adding AMP invalidations and are not AMP compatible.
 * Rest assure that those invalidations are been removed the AMP plugin but it also
   compromises the features that plugin adds on AMP pages.
 * AMP plugin adds site scan feature and Validation Tool to find and help users 
   and developer those plugins.
 * What you can do?
    1. Contact Plugin author ask them to make their plugins AMP compatible
    2. Look for mini plugin or extension that can help you fix AMP compatibility.
    3. Look for alternative from AMP ecosystem
 * Regarding performance
 * As I asked in my [previous response](https://wordpress.org/support/topic/site-scan-failed-4/#post-16590756)
   the major issues regarding AMP performance (mobile performance) are web stories
   images that are not properly sized for mobile screen
 * We hope this helps
