I was redirected here from the Epiphany bug tracker as you can see here : https://bugzilla.gnome.org/show_bug.cgi?id=777971
I am trying to login to my ebanking account (https://www.winbank.gr/sites/idiwtes/en/Pages/default.aspx), the site accepts my user/pass - no error indication - but after loading the page, it presents me with the same login page.
The site works with other browsers on the same system (Firefox 51.0).
The Web Inspectors output, where the only error I get is :
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (print.css.map, line 0).
I am using Antergos GNOME, Version 3.22.2 on the Wayland Display Server. Kernel version 4.9.6-1-ARCH. The WebkitGTK versions are webkitgtk3=2.4.11 | webkitgtk=2.4.11-4
