I am unable to disable read-only mode on my forum. IIRC I enabled it to take a backup, but now I cannot get rid of it: The ‘Disable read-only’ button in Admin > Backups changes to ‘Enable read-only’ when clicked, but upon reloading, the button returns to its original state and the site is still in read-only mode.
I also tried enabling after disabling and disabling again, but to no avail.
I have not received any emails of inactivity of my forum, so I don’t think that is the reason.
Can you try again now to see if you can disable read-only mode?
For some reason, our system was forcing your site to be read-only assuming that the second warning had been sent already. It’s possible it was triggered by changes made to read-only mode but we’ll look into it, along with another timing-related issue reported here.
