Access denied problem, please help

Hi, I am trying to upload something into a directory on my server but always i am getting a permission denied ONLY from this server...i have tried it on 2 other servers and they seem to be working fine but i have to get it working on this server as this server is the fastest and our production server. I have looked at the folder permissions and CHMODED/changed them from 644 to 766 and finally 777 but am getting the same error, i then had a look at the php info file (http://jumac.com/phpinfo.php) and i see file_uploading is set to 1 and 1, safe mode is off, i am not too familier with file uploading so is this right? if not, how can i change it? hopefully via a .htaccess as I dont have access to the php.ini file directly. These are my paths: $UserUploadDir="/usr163/home/r/y/ryanknig/public_html/BWH-Ads-Images"; $UserUploadURL = "http://jumac.com/BWH-Ads-Images"; Let me again point out that this problem only seems to be on this server, the scripts including the upload is working perfectly on the other test servers/sites.
