Hi Jeff,
That's really nice of you to come back to the forum and explain how you found a workaround.
I'd suggest you post a new message asking for help with the security problem. There have been a lot of discussions about how to deal with this but I'm afraid I wasn't able to understand them. Security problems are very real but they are potential so unlikely to come and bite you in the b.. in the first few days after you've installed Moodle. You haven't already got thousands of vulnerable 5-year-olds (like the blond kid in the green hat) enrolled on it, have you?
Cheers,
Glenys
