English into Dutch.
I think you mean in the preferences. But i want that everyone sees it in dutch, even if they aren't logged in. But if you don't mean it in the preferences, send me a link of the page.
No, this is not a user preference; this is a site configuration setting. To set it, you need to edit your "LocalSettings.php" file for the wiki (it will be in the root directory of the MediaWiki install).
I just made the wiki and there is written, Powered by MediaWiki. Do i have to install it still?
Do you have shell access to the server on which the wiki is installed? If so, you need to connect to the server's shell, go to where MediaWiki is installed, and edit the file 'LocalSettings.php' to add $wgLanguageCode = 'nl'; to it.
If you do not have shell access, do you have file access (e.g. through FTP)? If so, connect to the server's files, go to where MediaWiki is installed, download the file 'LocalSettings.php', edit it locally to add $wgLanguageCode = 'nl'; to it, and re-upload it to the server.
If you do not have shell or file access, I'm afraid that it is not possible to change how the wiki is configured like this, sorry.
I don't know where that is, the MDW installed thing. I do have a MDW:Sidebar and Sidebar-logo and Sidebarnotice. Can you search it for me? supermariowiki.thegamewiki.com/wiki/Hoofdpagina
You can't get to this from the web. You'll have to use a shell or FTP to find the LocalSettings.php file and change it.
Do i still have to download MediaWiki?
If you've already installed MediaWiki, you don't have to download it again. Assuming you have an existing MediaWiki installation, all you have to do is find its LocalSettings.php file and add one line to it.
Ok, but where do you find it usually?
In the directory where you installed MediaWiki, in the same directory as index.php and api.php
I didin't install it...
Ah, OK. In that case, look around in your public_html directory or whatever it's called, and try to find the MediaWiki files.
Uhmm... can you try to find it.
I don't have FTP access to your server, and it's not possible to find it via the web.
Can you say it then, i'll do it.
