From Mahara Wiki
From talking to people on the forums, these are the questions which I have actually seen frequently. We should probably put together some kind of FAQ page on the wiki itself, as part of the larger project of cleaning up and paring down the wiki so that it's more usable. For the meantime, I'll just put them here.
My page is dying with a short error message.
- Tell people how to activate error detailed displays
I get a completely blank page when I try to access my Mahara
- Tell people how to find the PHP error logs
