When I update to the most recent 3.7.2, I get this WP Dash message:
“Your database is being updated in the background.Taking a while? Click here to run it now. (100%)” but even when I click that link nothing seems to happen and that notification just remains.
The update of Hotel Booking plugin where this noticed can be removed has been released. Just update a plugin to 3.7.6 and click the link to finish the databse upgrade.
