The developer guide and user guide links on the [px4.io](http://px4.io) page send you to an empty page. I’m not able to access either guide.

Same here…  
I suppose they’ve already noticed and it will be accessible again soon.

Yes, we fixed it as soon as we could.

Normally I highly recommend this discuss forum over slack so that we can keep the legacy information about how things work and use it to populate our docs. However for time sensitive issues like this Slack is a better reporting path.

Thanks!

Hi,

When using https I get a certificate warning. Are you waiting for the certificate or do you still have to update the certificate chain?
