Not sure if your site meets the requirements?
After installing the plugin, check PDF Invoices → Dashboard — the Service status section shows compatibility information.
BridgeSync service connection
BridgeSync PDF Invoices uses cloud-based PDF rendering for high-quality, browser-accurate documents. Your server needs to connect to BridgeSync services.
Why this matters: The plugin sends document data to BridgeSync's PDF service and receives the generated PDF back. If your server can't reach BridgeSync, PDF generation will fail.
How to check: After installing the plugin, go to PDF Invoices → Dashboard. Look at the Service status section. You should see:
- "License active" — Your license is valid
- "PDF service OK" — Connection to PDF rendering service works
- "Schema OK" — Document templates are valid
- "API connected" — Real-time connection confirmed
If any of these show errors, check your firewall settings or contact support.
