I have a class called 'Motor' and have defined a link to another wiki page like this:
url of Motor is [[Motor]]
Now when i click on "Show preview" and move the mouse to class 'Motor' it shows the entire url
https://mywiki.brightman.de/spl/index.php/Motor
and when i click on the link, the url works. But when i'm not in preview mode but in normal mode and move the mouse to class 'Motor' it shows the url
https://mywiki.brightman.de/spl/index.php/User:Z007XT0M/index.php/Motor
So this link is wrong and leads to a non existing page, the fault is that 'index.php' appears twice in the url.
Is this a bug or a configuration issue? Thanks for any hints.
