In the 2nd page of installation, I can read:
Limite mmoire 5242880M
My php.ini is as follow:
memory_limit = 52428800
It's another way to fill the data, by specifing bytes only. So the formula isn't working here.
Page was: /piwik/index.php?action=systemCheck
(In ) fixes #1136 - get memory limit expects setting in megabytes
if(substr($memory, -1) == 'K') <====== shouldn't it be k not K? Or the use of strtolower() on the value? Perhaps a switch() statement would be better here (even if performance on this script isn't really an issue).
Thanks for fixing the bug.
