Hi,

I was wondering if there was any way to have a down page display when my forum is offline instead of the mybb default message?

Thank you very much for your help in advance

You can use Construction Mode.

You can create your own index.php or index.html file.

You can modify from the Vista Panel the error page to redirect to your costum error page ;)

Either use the Construction Mode plugin, make your own page, or if you are talking about if it is the wrong URL then edit the 404, 403 etc. pages.
