Hello, we attempted to upgrade mahara from 1.0.4 to the 1.1.2 version.  When we try to access the upgrade script we get

"Mahara: Site unavailable

And the log shows the following error messages:

Hi - interesting, that looks like a bug in Mahara. Your memory_limit PHP setting is set to 536870912 which doesn't have a suffix on the end to say what unit it's in. I presume it's bytes though. Mahara has crashed because it couldn't find the suffix.

Workaround for now: set your memory_limit setting to some value like '512M'.

Solution: we can patch get_real_size to assume bytes by default, in a future version. I have filed a bug for this.
