WooCommerce Data Update won’t run

I’ve updated to WooCommerce 3.0.4 but as yet have not been able to get the database update to run.

When I look at the log I see the following:

2017-04-27T11:39:45+00:00 INFO Queuing 3.0.0 – wc_update_300_webhooks
2017-04-27T11:39:45+00:00 INFO Queuing 3.0.0 – wc_update_300_grouped_products

2017-04-27T11:39:45+00:00 INFO Queuing 3.0.0 – wc_update_300_db_version

Please help.
Doug.
