We support many different ways to customize your WHMCS installation, all of which have their own troubleshooting needs.
To prevent problems, we recommend testing updates and customizations in a test environment before applying them to your production server.
Add a panel to the sidebar. This example adds a support information panel to the sidebar for support-related pages of the Client Area.
Add a Client Area Homepage panel. This example adds a customized promotional panel with a clickable button to the Client Area Homepage.
If you use custom templates, you will need to update them for any changes in new WHMCS versions.
Custom templates can alter the icons for the Client Area's Quick Shortcuts section. This section displays for Plesk and cPanel services.
Rearrange the Client Area navigation menus. This example customizes the display order of the items in the Client Area navigation menu.
