There can be multiple reason as for why you are getting Blank Page in vTiger. It can be server configuration, vTiger error, or a permissions issue. The first step you should do is enable error reporting in index.php. You can do that on the server site as well. To enable error report you will have to add an additional line to index.php. Go to “/vtigercrm/” Open index.php with your favorite text editor After <?php create a new line and add “ini_set(‘display_errors’, 1);” – (exclude double quotes). Save it Now you should be getting an vTiger error message instead of blank screen, which will help you to identify & solve the issue.
