  Help please I cannot log into my forum it returns the message "Maintenance Mode Forum is being upgraded please do not use it.

How do I sort this

Thanks

go to your site control panel (not SMF... your whole site)

edit Settings.php and set the maintenance variable to 0

or you can use repair_settings.php to do it for you.

What is repair_settings.php?
