#11 Hosting problem with a provider

[haberman]

I met no problem with easyphp but I have some troubles
with providers for hosting the application.

Providers disabled for security reasons some functions
like
ini_set('arg_separator.output', '&');
ini_set ('error_reporting', E_ALL);
ini_set('memory_limit', $ES_MEMORY_LIMIT);

Is that able to not use those functions ?

You can see the exemple on my web site at this
adress : http://www.hippocad.com/scheduler/

I try the same thing with an other provider and get the
same messages
