Updating the System URL
To ensure that your WHMCS installation can function, your system URL setting must be correct at all times.
After moving a WHMCS installation you must update WHMCS System URL to reflect the new location.
To update your system URL:
1. Go to Configuration > System Settings > General Settings.
2. Select the General tab.
3. Enter the correct URL in WHMCS System URL.
For example, if
example.com uses an SSL certificate and the WHMCS installation is in the
whmcs directory, the system URL would be:
In this case, starting the URL with
http://, omitting the
www, or other deviations could cause errors. The system URL must match exactly.
4. Click Save Changes.
