Upgrade Steps

To upgrade your current WHMCS installation to Version 4.5, simply follow the steps below. These same steps can be used to upgrade from any Version V3.3 or later.

  1. Begin by taking a backup of your database using a tool such as phpMyAdmin
  2. Now download the latest WHMCS version either from our client area ( or from the provider of your license
  3. Next, unzip the contents of the latest WHMCS zip file download to a folder on your computer
  4. Now remove the /images/logo.jpg file to avoid overwriting your customised logo image
  5. Next if you have customised your WHMCS admin folder name, you should rename the admin folder in the new files to match
  6. Upload the new files to your existing installation folder overwriting any existing files
  7. Visit the admin area as you normally would to login and you should then see the upgrade script
  8. Accept the license agreement
  9. Tick to confirm you have backed up your database and click the upgrade button
  10. Once the updates finish, delete the install folder from your server

The upgrade is now completed. The only thing left to do is update your custom templates if you have any with the new and changed template files for the new version. See below for details.

Release Notes

  • This upgrade will enable 2 new settings by default, Grouping of Similar Line Items and Cancellation Requests automated Invoice Cancelling. If you do not want these enabled then you will need to disable them in Setup > General Settings > Invoices
  • If you use the ResellerClub or any other LogicBoxes based module then in this latest release the modules have been updated to use ResellerClub's newer HTTP API for improved performance and reliability. And therefore after updating you should check over your configuration in Setup > Domain Registrars and ensure your servers IP is allowed in the LogicBoxes control panel. More info on this can be found in the ResellerClub page
  • If you use the 2CheckOut module, you will need to reconfigure and setup the 2CheckOut INS service after upgrading to V4.5. Please refer to the 2CheckOut page for more details
  • If you use the Live Chat Addon then a licensing update is needed for WHMCS V4.5. This update can be downloaded @ and the files from that simply need to be uploaded to the WHMCS /modules/livehelp/ folder for it to take effect.
  • A number of users have reported issues with their admin area constantly reloading after upgrading. This has been identified as being caused by having an old cached version of jQuery in your local browser. So clearing your temporary internet files and doing a hard refresh should prevent & resolve it.
  • Patches/Updates - As any issues that arise in the new release that get reported to us and fixed, we will be posting them in a dedicated thread on our forums @ to save you needing to contact and wait for support
