Some sites will not allow 1P to save login details.

Hey michaelwayne,

I'm sorry for the trouble you are having on this website. You're right, 1Password is having a hard time detecting the login fields. I have filed an issue with our development team to see if we can improve the behaviour on this page in a future update.

In the meantime, I have found I was able to fill by clicking on the 1Password icon in the browser toolbar followed by 'Autofill' next to the item.

I understand that this isn't ideal, thank you for bringing it to our attention.
