This is probably really easy...but since I'm not that used to playing around with permissions and mount-options, some assistance would be nice:

I use XAMPP to test my webpages. Whenever XAMPP is running, localhost points to opt/lampp/htdocs/. Normally, I would just paste a link inside opt/lampp/htdocs that points to the folder I wish to access from my browser. However, now that the link is pointing to a folder located on my mounted TrueCrypt volume, I get a 403 (Access forbidden).

I can't seem to change the permissions on any of the folders on my mounted TrueCrypt volume, hence the 403. Any suggestions?
