Everything seems to be working except registration. Filling in all the fields still gets the message:

"All of the required fields are not filled in."

Where do I begin to trouble shoot this problem since no can complete registration.

Thanks

For testing change the registration settings in the
control panel from required to not required.

You can then keep turning them on one by one
until you find the field that's causing the issues.

There have been some issues with "0" a zero
in one of the fields but cant remember which one.

And i think its fixed for the latest release 7.2

Make sure that you don't have both the "Birthdate" and "age verification" features enabled; in older versions this will not allow you to continue (as the birthdate is retained on the one step and doesn't show on the second)
