That's the error i get when i paste my wiki url.

I tried with a new installation of mw1.29.2 on Sunos 5 and found out, that if i use /wiki/$1 then the wiki functions (also with mw1.23) - with only /$1 (what i need) i get '500 internal server error' Can the reason be a for me unaccessible server-variable ?

https://www.mediawiki.org/wiki/Manual:$wgScriptExtension/de removed in mw 1.27 --- in redwwerks used as $wgScriptExtension = ".php";

I used this for above : without /w and /wiki like spiritwiki.de and no result
