I can't edit Common.css though I have the interface admin rights. What's wrong?

Are you getting any error messages when you try?

I have no edit tab and it says: "Du bist aus dem folgenden Grund nicht berechtigt, diese Seite bearbeiten:

Du hast keine Berechtigung, diese JavaScript-Seite zu bearbeiten, da sie alle Besucher betreffen könnte."

"You have a permission to edit this Side: You have no permission to edit this JavaScript-Side, cause it ca affect all users."

"no permission" not "a permission"

Check on your wiki's Special:ListGroupRights whether the interface-admin group has the editsitejs user right. If it does, double-check on your wiki's Special:UserRights whether your account is actually an interface admin.

I've have both. Can there be anything missing on Server outside Mediawiki?

Are there any other editors on your wiki who are interface administrators? If so, are they able to edit your wiki's MediaWiki:Common.js?

For that matter, what happens if you try to edit your wiki's MediaWiki:Common.css?

no. i'm the only one. Mediawiki:Common.css is exact the page i want to edit

Oh, sorry about that, I somehow got mixed up about which page you've been trying to work on.

In that case, you should check to make sure that the interface-admin group has the editsitecss right.
