I just did some upgrades. They all seemed to go well, including a database upgrade. No error messages or anything. However, when I tried to either access the site or return to the dashboard I just got a message saying:
Briefly unavailable for scheduled maintenance. Check back in a minute.
This is despite getting the following message following the updates:
Disabling Maintenance mode…
All updates have been completed.
Now I can't access either the site or the dashboard. I'm pretty sure that maintenance mode shouldn't be enabled, so is there any way I can turn it off?
