Support » Plugin: SiteGround Optimizer » The presence of the page cache cannot be detected

  • Resolved Giuseppe C.


    I have numerous sites on siteground in both client and personal management.

    Immediately after upgrading to WP 6.1.1 and only for this site I get the 4 recommended improvements and in particular the last one “It is not possible to detect the presence of the page cache”

    Both on the server side and from the front end there are no errors and also other sister sites with the same theme and plugins do not have this warning

    Hello @sitiwebagencyeu,

    I checked the cache-related headers of the reported website and I was unable to find any issues with them. The headers are correctly returned along with the required values. Also, I was unable to replicate the issue in my test environment.

    The errors in question are usually caused by plugins, so you can try disabling the plugins one by one in order to confirm that. If the issue still persists, please open a new ticket from your SiteGround User Area so we can investigate the case further.

    Thanks Dimitar in fact I can confirm that of all the sites managed on siteground this is the only one that generates alerts. Will try the plugin deactivation procedure as soon as possible. Best regards
