Website documentation is not working

[daniel-zazula]

If you navigate to https://pgwjs.com/pgwmodal/ on Google Chrome, then click on Example or Documentation, nothing happens.
Google Chrome's console shows the following error:

Uncaught ReferenceError: pgwjs is not defined
at HTMLAnchorElement. ((index):280:38)
at HTMLAnchorElement.dispatch ((index):272:44520)
at r.handle ((index):272:41249)

seems the pgwjs domain has expired. anyone know where to get the documentation?
