How to choose whether existing customers have to re-sign new terms and conditions

1. Go to Settings > Customers > Registration settings.

2. Once you have uploaded a pdf document of your terms and conditions, you then have the option to Require customers to re-sign terms and conditions.

If set to Yes the customer will have to agree to the new terms and conditions when they next log in to their account.

If set to No the customer will not have to agree to the new terms and conditions when they next log in to their account.

Note: Any new customers will have to agree to the terms and conditions upon registration regardless of the setting mentioned above if there are some uploaded. Existing customers will only have to agree to the new terms and conditions if you upload a new document at the time of changing this setting to Yes. 

3. Once you have finished, click Update details.
