After upgrading Wordpress to 5.8 and CiviCRM to 5.39.0, the event registration page does not work.

This is the url:

  • MY-SITE/civicrm/?civiwp=CiviCRM&q=civicrm%2Fevent%2Fregister&reset=1&id=120

These are the symptoms:

  • the h1 of the page is "CiviCRM"
  • the body of the page is "Do not delete this page. Page content is generated by CiviCRM."
  • the title tag in the header contains the title of the event
  • no profile fields, hence no possibility to register for the event.
  • no errors in ConfigAndLog
  • no javascript errors in browser web developer tools
  • several cache clear had no effect

What could be the cause of this error? What can I do to debug this further?

You will need to comment out line 526 from /includes/civicrm.basepage.php

remove_filter('the_content', [$this, 'basepage_render']);

That should solve it.

    Thanks a lot, Tommy! Commenting out that line and clearing WP and civi caches solved the problem.

  • @AlainB are you using Divi or Avada Theme?

  • @TommyB Are you finding this problematic on all sites or just those using themes like Avada and Divi? Commented Aug 4, 2021 at 19:02

    @KevinCristiano only Divi so far -- I only suspect avada --- This plugin looks like the long term solution github.com/phdccltd/civicrm-539-wp-content-fix

  • @TommyB It seems that the guy who made the site used the Ken theme.
