I'm getting a blank or partially loaded page

[Matt]

If at any time you encounter a blank page in the WHMCS system then this indicates a fatal PHP error is occurring. Error display is turned off by default for security so in order to see what error is occurring, you need to enable error display. First please ensure display_errors is enabled in the server's PHP configuration and enable the Setup > General Settings > Other tab > Display Errors option, then reproduce the blank page problem.

You should now see an error output to the screen. We have collected some of the most most common errors and their causes, refer to the appropriate page in the following sections:

• http://docs.whmcs.com/Server_Modules
• http://docs.whmcs.com/Domain_Registrars
• http://docs.whmcs.com/Common_Troubleshooting_Tips#Server_Errors

If you are unable to access the admin area to enable this option, or you are running version 4 and earlier add the following line to your WHMCS configuration.php file instead and then reproduce the blank page problem. Once testing is complete, be sure to untick the option or remove the $display_errors line again from that file so that clients aren't getting warnings or errors.

$display_errors = true;

Often the error message will be explanatory enough for you to identify what the issue is. Common problems are errors in custom modules, hook code, template customisations & variables, or entirely missing/non-updated files.

If a blank page still occurs please refer to the following page in our documentation for further troubleshooting steps: http://docs.whmcs.com/Blank_Pages

By following the above before reporting the issue and including the error message when posting you'll be helping the community to help you more quickly.
