OK... I have just done a full install with a two day old download and all is fine...
PHP Version: 5.2.0
MySQL Version: 5.0.22
I'm at a loss as I can't test MySql 4.1.1... I googled for php + mysql 4.1.14 problems and found several but I can't determine if the updated code is responsible. We need to check if anyone is using this combination successfully... Back to searching for now...
One suggestion would be to temporarily replace functions_profile .php with older copy and see if the error was the same... it's worth a try...
If we can identify where the problem is we might be able to find a fix for it without having to upgrade versions which if almost definitely the cause as this problem only surfaces with these versions/combinations (so far)
