Although we haven’t been able to replicated this error on our own servers yet, we believe the error is due to a javascript error. Unfortunately, it appears that this javascript error is not our fault (If it were, we would fix it), but rather the result of incompatibility issues with other javascript scripts from other plugins, custom hacks, or themes.

For now; we have updated Business Directory so that the submit button is not dependent on javascript to function properly. If you have been experiencing this error, download Business Directory again and reinstall it.

We have uploaded a quiet update as of October 13 at about Noon.

Details about the update: We have inserted a small bit of code that allows the Submit button to function even if there is a conflict with another javascript (such as, we think, Google Adwords). Users experiencing a conflict will not get the auto-populated instructions in each of the entry fields of the Add Form, but the Join button will still work. Users with no conflict will experience things as normal.

We have a plan for a more robust fix in future versions.
