CiviCRM/PHP/Smarty Contribution Page Repair

A functional Drupal/CiviCRM website has an error or bug in the TPL file governing the function of the contribution pages. The template appears to be sites/all/modules/civicrm/templates/CRM/common/CMSUser.tpl. The symptom occurs when an non-authenticated user who has an account on the system is attempting to renew their membership. The CiviContribute page they access asks them to either: - fill in a number of fields to establish a new account (this is not the correct option as this visitor already had an account) OR - log in (this is the correct option for this visitor to take). The visitor is then taken to the login page. After logging in successfully, they are taken to the home page of the site instead of the respective contribution page from which the login page was launched. The login redirection routine needs to be replaced with a dynamic PHP parameter that catches the respective contribution page, and relocates to that page after logging in. This is not a difficult task for someone well versed in PHP and Smarty. ## Deliverables Payment will not be made if: - Any/all original files are not first archived on my server where I can get to them, and their location provided. - Any existing functions are damaged or otherwise rendered useless.
