HTchat Live Chat for WHMCS - v1.0.0
Requires WHMCS 8.x and PHP 7.4 - 8.3.

INSTALL
1. cPanel > File Manager > open your WHMCS folder (the folder that has
   configuration.php, e.g. public_html/billing).
2. Upload htchat-whmcs.zip there and click Extract. Keep that same folder as
   the destination. Files land in modules/addons/htchat/.
   Do NOT extract into public_html or into a new sub-folder.
3. Delete the ZIP after extracting.
4. WHMCS Admin > System Settings > Addon Modules > HTchat Live Chat > Activate.
5. Click Configure: paste your widget key (starts with htc_, from
   htchat.app > Settings > Installation), tick "Show in client area",
   choose Access Control > Full Administrator, then Save Changes.
6. Open your client area in a private window. The chat bubble appears.
   HTchat marks the site as connected on the first visit.

UPGRADE: extract the new ZIP in the same place and allow overwrite.
Settings are kept (they live in the WHMCS database).

REMOVE: Deactivate in Addon Modules, then delete modules/addons/htchat/.

TROUBLESHOOTING
- No bubble: check the key starts with htc_, "Show in client area" is ticked,
  and clear any WHMCS/Cloudflare cache. Open Addons > HTchat Live Chat for status.
- Custom templates must keep {$footeroutput} (all standard WHMCS themes do).
