Ini_set() issue, can't access panel

Hi!

I just put my website online, but whenever I try to connect to the panel, I get this error:

ini_set() has been disabled for security reasons

Any idea where this comes from?
I tried creating the php.ini file and add the following line but that didn’t change anything.

disable_functions =

On local, it works fine.

Maybe the ini file is ignored, I suggest you contact your hosting provider with this problem.
