Hotspot login redirects to IP-Address of Gateway instead of host name of hotspot

Hi,
After doing some more testing, this benhaviour seems only to happen when I change the hotspot default directory in the hotspot server profile. Problem is that I cannot access wherever the default files for the hotspot are stored (http://forum.mikrotik.com/t/rb4011-missing-flash-directory/160596/1).
The device in question is RB4011iGS, now running ROS 7.5 (as of today).
Any assistance would be great.
Thanks…
