[eGroupWare-developers] Separator bug

[Zombie R. <zom...@ya...>]

[Thu Dec 11 00:07:56.642401 2014] [:error] [pid 16363] [client 
192.168.0.252:37040] PHP Fatal error:  require_once(): Failed opening

I take it that somehow SEP should be a "/" why would eGroupware fail to 
translate this? I have tried

define('SEP', "/");
It didn't help.
