we have a problem with expired members renewing.
When they renew using our webform, the old membership is replaced completely with the new membership. This means we lose the key 'member since' data.
They also show as a new member and not a current member which presents problems for us.
This does not happen when someone is in the grace period. This does not happen if we manually renew the expired membership.
We use webform civicrm intergration with paypal standard. Drupal 7. Latest version of webforms and civicrm intergration. CIVICRM 4.5.8.
Any help resolving this issue would be much appreciated.
Thanks, Andy
