Question Kunena backand doesn't work

Hi,this is my first post on this forum,and have to say,i love your work ppl.However I could't find answear to my question nowere on the forum.Ehm,here it goes-I have instaled Kunena on my site on localhost,tested ewerything,whan I was finished site was published and ewerything was fine,worked great,but since this morning i can't change data in the backand of my site for kunena(frontend still works great,no problems posting,etc),whan i check what I want to change it just bring me back to the home page of administrator backand of Joomla! website.So I was wondering what could be the issue here.Ewerything alse on website working great btw,without any problems...

Hello,

Can-you please give details on what are you doing in backend ?

want to change who sees user list (to just registered) and few more things,but it want except changes...
If you mean did I install anything etc,no I haven't,which is why I'm confused,ewerything was normal and just bum,can't change kunena configuration in the backend...

Also what's interesting is that it seems that ewerything alse works great,adding of moderators,administrators,smilies...

Do you have tried to enable debug mode in joomla and kunena configuration panel ?

In Joomla! yes,but problem is that I can't turn it on in kunena because,as I said entire Forum Configuration part want react.I change settings,click save and he just send me back to the Joomla! default administrator backand without any changes done...need the debug code?

Look in php or apache log if you something
