I am using WP 5.4.2 - PHP 7.2 - CiviCRM 5.27.3 - the Plugin lite-speed 3.2.4 is activated. UAT has raised this issue : "the browser session has expired you are unable to complete the event form subscription"

I see those post : All Contribution pages result in "Your browser session has expired" "Could not find a valid session key" Intermittent "Your browser session has expired and we are unable to complete your form submission" errors

And I understand the root cause is "cache management". Yes: if I delete cache on the host-admin the form is now available to the end.

Someone said the solution is :

Based on further investigation and discussion this seems to have been related to the WP Super Cache "Don’t cache pages with GET parameters. (?x=y at the end of a url)" setting being disabled.

But I don't understand if the fix is to be done :

  • on WordPress = modify WP Super Cache
  • on Lite-speed plugin = desactivate it
  • on the Host = ?

  • Can I ask for some more details? Are you using Cleaner URLs? Does the event page look like https://wpcv.test/civicrm/event/register/?id=1&reset=1 or https://wpcv.test/civicrm?civiwp=CiviCRM&q=civicrm%2Fevent%2Fregister&reset=1&id=64 The Starting page for the event signup is it a WP page using a shortcode? Lastly, what is the URL it attempts to get to on the second page? I agree caching is the issue and the above will help in suggestions on how to cause the pages not to be cached.

thank you for your answer. Yes I am using "WP Cleaner URL's": -the starting page seen in civicrm-admin is: /event/info/?reset=1&id=2

The website is hosting by Hostinger that advice to activate LiteSpeed from his admin-page: it is LiteSpeed Cache 3.3 with defaut settings. As a first step I decided now to

  • un-activate "Mettre en cache les utilisateurs connectés"
  • un-activate "Server stale"
  • set "shedule purge time" at 00:01

Thank you for suggestions
