I tried upgrading to 5.24 and it hung half way through the upgrade - while upgrading to 5.24alpha1. Here's all that was in the log - it then died. I've gone back to 5.23.4 (Drupal). Ideas?

Apr 02 09:21:30 [info] Running task: Cleanup old files
Apr 02 09:21:31 [info] Running task: Checking extensions

Apr 02 09:21:34 [info] Running task: Install sequential creditnote extension

  • Did it succeed in installing that extension? Are there any errors in webserver logs, or CMS logs?

  • I restored the database, which is shared with Drupal, so the only thing I have is the above log. I'll retry the upgrade and look further

  • I ran the upgrade again, nothing in civicrm_log or Drupal's log, nothing more in ConfigAndLog, and no extension installed. I can try again with some diagnostics. Also I do have a lot of extensions, I could do some gradual disabling. This is a test system, by the way!

  • Ok, since it's a test system would be interesting to try installing that extension manually after the upgrade has failed and see if you get more error messages that way.

  • (a) +1 for disabling some other ext's as debug tactic. (b) You might get better debug info with one of these patches: gist.github.com/totten/96aa7172faced3fde2225e145307f3b9 (c) You might also get more debug info with a CLI runner (eg cv upgrade:db -vvv).

I was able to reproduce a similar symptom in a wp-demo configuration. Specifically, the upgrader activates the new, core-internal extension (sequentialcreditnotes), and the activation fired off a general system-flush, and the general system-flush raised an error while handling some data from another extension (civivolunteer). The problem only occurred with the web-based upgrade UI (and not with the CLI-based upgrader).

CiviCRM 5.24.1 has a fix for that case.


On WordPress version, tried to upgrade from 5.21.2 to 5.24.0 twice and had the same issue. Freezes on: Executed: Upgrade DB to 5.24.alpha1: SQL Had to restore previous day's back up to bring database back. No error messages, just the freezing.

  • I was able to reproduce this problem. The following fixed it for me: github.com/civicrm/civicrm-core/pull/16971

  • I saw the same under Joomla. My test Joomla instance ran to completion, but the CiviCRM menu disappeared! Commented Apr 4, 2020 at 14:39
  • Glad you found a fix, Tim and thanks for letting us know . I'm surprised this didn't occur in testing as it was such a solid error.
