I did my research before commenting.
1. There is no one point source in DH documentation to say how this problem should be fixed, particularly when this is a common issue.
2. There are posts and discussions around this topic by users but not by DH itself. Shouldn't it offer this when they attract users using "one click" Moodle install as a selling point?
Even if custom php.ini's are possible, why use such a limit in default settings that is unrealistic? One-click install, but with unrealistic settings. May be I am not an expert and hence am finding this a bit hard.
As I said, I am not complaining, just observing.
sXi, the link you sent was awesome. Thanks.
