Editing php.ini need help with question

Hello im wondering if the newer 4.0 version has the increased upload post and etc required for uploading sermons the documention says that you need to make changes to the php.ini. I don't have a clue how to even get into this file with joomla 1.7 so im hoping that with issues in the past that made the doc file add this change that maybe the software people when they did another upgrade they increased these settings so the user won't have to . Im new to joomla so im lost on how to even view or change this file

The php.ini is a file needed by your server. It tells him how to run PHP (the programming language Joomla and SermonSpeaker are written with).
On hosted servers, you often can't edit this file yourself. It's configured with some default values by your hoster. You need to contact him and ask him if he raises the values. Usually he will do this without any problems.

SermonSpeaker 4.x doesn't have any increased requirements in this regards, I'll probably just added them to the documentation because some people had problems with low settings.

Ok thanks
