Installing and upgrading help

I am very familiar with this problem:

ERROR: Could not find or create a directory (/home/edusonl/public_html/moodle/uploaddata/11)

It has been with me since I started using Moodle. I had a friend help me work out this same problem in the config.php file about two years ago when I first got started. Things worked fine, even when I upgraded to a newer Moodle version. At least, everything seemed ok.

However, I restored my courses from the old site to the new site with the new Moodle. The old files have moddata files but the new classes do not have these files. I have tried to manually create them but I no longer have administrative permission.

How can I create these new moddata files? I am instructed to change the Admin permissions, but I feel like I've tried everything within the course settings.

Should I be working with Administrative settings or config.php?

I am not very expert at PHP, but I am willing to keep plugging away at this problem till I understand it.

Thanks
