Can you give me some hints about what can be the problem? I built openkm both with the build.sh script and with eclipse but the result is the same.
I attached a screenshot of the website as can be viewed by the user.

Thank you in advance.

I refer to the OpenKM taken from sources at revision 7776.
I prefer to avoid updating because I made some local modifications and updating brings to many conflicts..

Or maybe can you say to me a revision that is pretty stable so I can update to that one?

Actual version 6.2.2 corrects some bugs, you can consider as stable. In you case you should debug with GWT. When this problems happens first refresh browser ( sometimes is a problem with browser cache. If it's not the problem then you should debug with GWT as is indicated here http://wiki.openkm.com/index.php/Debugging_with_GWT and in Main.java you should enable debug to on ( by default is off and you'll not see the error ).
