We've introduced a new option in B2B Handsfree's settings. If you ever need to recreate B2B Handsfree's default registration page template – for example, if you edited the template and introduced errors into the code – you can now force a rewrite of the template.
Note that this will overwrite any customizations you might have made to the template. So it's probably a good idea to back up the customized template file before rewriting it.
