on the contactcare.php page, all of the require once lines are pointing to the admin subdirectory, for example:
<?php require_once("admin/webassist/form_validations/wavt_scripts_php.php"); ?>
<?php require_once("admin/webassist/form_validations/wavt_validatedform_php.php"); ?>
those should be looking for the webassist directory at the same level rather than in the admin directory:
<?php require_once("webassist/form_validations/wavt_scripts_php.php"); ?>
<?php require_once("webassist/form_validations/wavt_validatedform_php.php"); ?>
there are other similar require once lines that will need to be changed too.
