403 forbidden

hi guys,

i know this is a popular topic so sorry for re-posting but here is my problem..

i created a subdomain in cpanel where i want to install wordpress so it doesnt interfere/over-write the site that already exists. i created a /subdomain and uploaded/extracted the wordpress file so now i have /subdomain/wordpress <— where all the files are. i ran through the install screens (title, admin user, pword, etc) but when i log into my index.php file i get the following error “403 forbidden – You don’t have permission to access /”subdomain”/wordpress/ on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”

from the other posts on this topic i figured i needed to create a new .htaccess file in the /wordpress folder where the index.php file is and adjust the line in index.php that points to the wp header file but no dice.

any advice/suggestions? i kept the .htaccess file in the root public_html folder as is – do i need to make any adjustments there? i dont want the site as it is now to redirect or anything, i just want to install wordpress and create a new blog while the old site stays as is.

thanks so much!
