"Request entity too large"


I was wondering if someone could help me as i am a bit of a noob to Websites.

I currently have a blog at www.liveitwithless.com running on wordpress Thesis theme.

Yesterday I was changing post layout in Thesis Options and has now frozen up anytime I want to change it?

I get this error message,

“Request Entity Too Large”

“The requested resource
does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit”

Thesis forums are saying its Dreamhost limit in php.ini file and they can change, however Dreamhost support says that I need to change it??

I have had a bit of search but cant seem to find easiest method to change the php.ini file so that I can increase limit.

Pls help as blog now looks weird with all posts as exerpts
