title: vtiger 6 can't add user
body: <p>When I try and create a user, it goes to a blank white page.  When I go back to crm, no user was created.  Is there a fix?</p>
  
  <p>so for example there was another issue where webforms did not want to save.  so i applied a fix i found somewhere which was to add a database table.  the code for that is below.  so i was looking for similar help with this new issue above.  don't know if it's going to be a mysql modification or a php modification, but hopefully someone knows something.</p>
  
  <pre><code>CREATE TABLE `vtiger_webforms_field` (
  `id` int(19) NOT NULL AUTO_INCREMENT,
  `webformid` int(19) NOT NULL,
  `fieldname` varchar(50) NOT NULL,
  `neutralizedfield` varchar(50) NOT NULL,
  `defaultvalue` varchar(200) DEFAULT NULL,
  `required` int(10) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `webforms_webforms_field_idx` (`id`),
  KEY `fk_1_vtiger_webforms_field` (`webformid`),
  KEY `fk_2_vtiger_webforms_field` (`fieldname`),
  CONSTRAINT `fk_1_vtiger_webforms_field` FOREIGN KEY (`webformid`) REFERENCES `vtiger_webforms` (`id`) ON DELETE CASCADE,
  CONSTRAINT `fk_3_vtiger_webforms_field` FOREIGN KEY (`fieldname`) REFERENCES `vtiger_field` (`fieldname`) ON DELETE CASCADE
