Can't activate notify push

[KodeIn]

Tried to activate notify push from yunohost admin interface.
But I got a bunch of warnings about cron, then it fails.

Looks like it's a known bug that got fixed recently upstream in 33.0.5 : nextcloud/notifications#3035 (comment)

I don't have the issue with version 34 (on testing)

I forgot to say that I got notify push to start (still with many of those cron.php errors) but get no notifications on my clients.
When I use the android talk client to test notifications, it sends back an http error 500, like what's described in the github link. I also get the error saying that it can't delete notification when using nextcloud from the web page, which is another trouble linked to the same bug. It's a known bug that got fixed in 34.0.5 but still there in 34.0.4

Oh, and it's a fresh install since the upgrade to 34.0.4 failed badly and for some reasons it couldn't restore the backup.
