Just for reference I made a post at Korean Random:
http://www.koreanrandom.com/forum/topic/23985-cant-change-settings-from-website/
UPDATE: On a whim I tried the Aslain's MODPACK install and its working perfectly.
K So i tried reinstalling the mods and still the same problem. Also I tried changing the settings at the xvm site on a different browser and still the same problem. I will move this along to koreanrandom. Thanks Aslain for being patient and very helpful. Cheers!
I'll try to do a fresh install with only xvm config.
I've attached a screenshot of what I am getting along with the python log.
The XVM settings are set to default(not 2 digit) and XVM.
python.log
I have this same problem and changing the XVM website settings doesn't change it.
I have three mods installed.
Aslains XVM MOD
Jimbos xhair
Yasen Krasen
These are not installed using the MODPACK.
