 * Hello there [@susanna961](https://wordpress.org/support/users/susanna961/)
 * Thanks for the info.
 * I can see that the last time you generated critical css was on Monday and it 
   was successful.
 * Successfully generating Critical CSS should clear the diagnostics. Updating a
   page, post, enabling/disabling a plugin or switching a theme could cause it to
   show that Critical CSS is outdated.
 * Could you try generating again and then without any other interactions with the
   site, go check on the WP diagnostic? It should be cleared up.

 * Hi there, [@susanna961](https://wordpress.org/support/users/susanna961/),
 * Do you have updates about that, do you still need help? We usually close inactive
   threads after one week of no movement, but we want to make sure we’re all set
   before marking it as solved. Thanks!
