[Mediawiki-l] Mediawiki Problem - can't edit anymore

[Karin Rafael Remeikis]

Hi,

have this site http://spaceweek.de - (german link) - and since 6 month I try
to find the mistake....don`t know why I can´t edit it anymore...when I login
as admin it seems that the edit buttom can not be loaded and therefor the
sites are just white (can't load) ....when  I login as burocrat it is
possible, because there is no edit buttom included.

Checked the files localsettings and change "false"  to "true" - but it also
didn't work....does someone has an idea what I can do? I also would like to
mak an update ...perhaps I shall delete everything and do it again...am
grateful for any help or advice.

Thank you.

Karin
