Licensing​

How does licensing work?​

Installation​

Where do I upload the files?​

The module doesn't appear in WHMCS​

  2. Ensure port 2087 is open
  3. Check firewall allows your WHMCS server IP

Features​

Why can't customers see certain features?​

Feature availability depends on:

  • cPanel package limits
  • Server configuration
  • Account type (User vs Reseller)

File uploads fail for large files​

Large files (>50MB) should use the "Upload Large Files (via cPanel)" button which opens the native cPanel uploader.

Email accounts not showing​

  1. Verify email feature is enabled in cPanel package
  2. Check disk quota isn't exceeded
  3. Verify domain is properly configured

Databases not appearing​

  1. Check database limit in cPanel package
  2. Verify MySQL is running on server

Reseller Accounts​

How do reseller accounts work?​

Reseller accounts get access to WHM features and can create/manage their own cPanel accounts.

Can resellers access client accounts?​

Yes, resellers can manage accounts they've created through the WHMCS interface.

What ACL should resellers have?​

Create a custom ACL with only the features you want resellers to access. At minimum:

  • create-acct
  • suspend-acct
  • list-accts
  • passwd

Troubleshooting​

"Service ID required" error​

This usually occurs when the session has expired. Refresh the page and try again.

Slow loading times​

  1. Check server response times
  2. Verify no firewall rate limiting
  3. Check PHP memory limits

SSO (Single Sign-On) not working​

  1. Verify API token has session creation permissions
