404 bij accessing admin

[catany]

If I try to access the admin section with the line
http://linknou.info/admin
http://linknou.info

Can someone help me? I think it is a stupid error
.htaccess

hello
i saw the error :

Table 'mata.Arfooo_settings' doesn't exist

you should not change the names of fields in database ! Nobody saw them, but the script need them !

you can change the tables name, but only when you are on the install interface (or if you are a advanced user)...if its only a configuration problem just check the file config/db.php

also, i would recommend you to only use lower case in the sql names
