I upgraded two Joomla sites from 5.8.x to 5.9 and one of them now gives an error for anonymous contributions or membership registrations:

Error:

Database Error Code: Cannot add or update a child row: a foreign key constraint fails (`zzz`.`civicrm_acl_contact_cache`, CONSTRAINT `FK_civicrm_acl_contact_cache_user_id` FOREIGN KEY (`user_id`) REFERENCES `civicrm_contact` (`id`) ON DELETE CASCADE), 1452

Additional Details:

This matches a similar issue after 5.9.0 upgrade: DB Error: constraint violation on anonymous user event registration after 5.8.2 -> 5.9.0 update

I have Mail enabled. The error doesn't occur when logged in so I've matched and then enabled more permissions than the other site which works, but it makes no difference.

This is a core bug and Eileen has send a PR for the fix. Will you be able to try by applying the patch from here?

If the patch works for you than please comment your test result on PR so that it will speed up process of merging into core and having it available in next release.

Cheers

This is fixed in 5.9.1 ............
