Attempts to 'log-in'

[bcnaz]

I have been logging into the forum for a few years now.

I prefer using Epiphany (Web) however I just tried 8 times to log in and it would not let me, something about mis-matched credentials ?

I switched to Firefox and logged in on the first try.

I am using DuckDuck on both browsers.

Is there a problem with the forum or website software blocking Epiphany from logging in.?
  I was able to browse the forum with Epiphany before I tried to log-in.
