Re: [xwiki-users] Can't use IP as pagename, why?

Hi, I tried to reproduce your problem but didn't manage to... Can you provide more information about the steps you're following ? - is your user logged-in when he creates the topic ? - has you done anything special with your rights setup ? - has the page been saved once before you create the topic ? - what version of XWiki are you using ? - does it do this with every new topic you create ? - is there any other code on the page ? - etc...

[xwiki-users] Top Menu header-Groups
Hello, In my wiki, I granted the rights for the top menu header bar to be showed only to administrators by using #if($hasadmin.#end) in the menuview.vm file. Now I am faced with extending this right to members of a certain group only in one space rather than the entire wiki. How would this be possible as I already tried setting a new parameter ($entry=entry) and trying to pass it in the menuview folder. This did not work as the header was disappeared the entire time. What would be the best way about going along with this since when you simply grant rights, the menu bar does not appear?
