[SOGo] ios interface messed up

[Purga]

My Ubuntu 14.04 LTS SOGo 3.0.1 interface looks good on Desktop
(chrome/firefox) and Android (chrome/firefox),
but messed up on ios 8.4 (both iphone/ipad, using firefox/safari) just
after logged in:

I've enabled the verbose mode in /etc/sogo.conf but didn't find anything
useful to tackle.
Any hints maybe?

Thanks,
