No Input File Specified - Revisted


I have installed b2evolution and all default blogs run well, although any NEW blogs I create always generate the “no input file specified” when i go to the link. I know this is related to running php as cgi, but i dont know why only my new blogs give the error, or how to fix it. Im new at php so somebody please give me the steps to fix this. I cannot run my blog until I do. Thank you,
