You have installed vTiger 5.x and once you login you get a message “Module name is missing. Please check the module name.” If it’s a fresh install, most likely the $root_directory variable in config.inc.php is not set properly. In order to set it, do: Go to folder vtigercrm/ Open config.inc.php file Find $root_directory variable and make sure, your vTiger CRM path is correct. Once verified, try again, if it still doesn’t work do: Add “/” at the end of the path, for example: /home/content/98/html/demo/ Try again, if it still doesn’t work try: Add “/” at the beginning of the path (if it does not exist)
Finally vTigerCRM 6 Beta have been released. It’s not fully functional yet, there are some modules missing as well as some new modules that did not exist in vTigerCRM 5.4 such as Google Calendar & Contact Sync. Since it’s just Beta version, you can not upgrade from 5.4 yet and it’s only for testing and bug reporting purposes. The RC/Stable is scheduled to be released September or October, however the schedule might change. Vtiger 6.0 Beta: Installation Files | Installation Manual | Developer Manual
