[Koha] support request? does anything need to be edited in a web based install before running the installer.pl

Dear Koha contributor, - a quick question if you will for a non-profit http://alexandriawest.org/ - Does any file need to be edited when installing to a web host server (ftp uploading Koha to a cgi-bin) for a web site? Does the config file in the main koha file need to be edited or will the installer.pl script do that? I am having trouble getting installer.pl to start (from the web browser) and thought that maybe I missed a step. I get access denied and 500 when trying different things. I set the chmod to 755 on as many files as I could find. best regards, Mr. Truth Collins "The task is arduous but every effort brings strength and joy," Raghavan N. Iyer
