The installation of the addon is not working

We installed the WHMCS addon and configured it as instructed but the buttons don't show on the pages. The links are to the screenshots of all settings.

1) Port 80 status
2) WHMCS Setup
3) OneAll code inserted in ClientRegister.tpl
4) OneAll code in login.tpl

What should we do?

Thank you,


  • We tried the plugin downloaded from github and your site.

    could you please send me a link to your WHMCS ? I will have a look.

  • hi ...

    I have installed WHMCS plugin latest version from your github

    but I got this error in my login page :

    Uncaught ReferenceError: OneAll is not defined

    could you tell me which version of WHMCS you are using?

  • We encountered the same problem while the Rocket Loader (Cloudflare solution for script loading speed) was active. When the RL has been deactivated for the login page, the issue has been fixed.
