Warning message: Cannot execute using backquotes in
safemode in /..../installer/lib/inc-generate.php on line
158

This Warning I get when I try to install the Jukebox. It
appears after I click at the acceptbutton on step 3 of
the install.
Very weird, even after chmod the file to 777, it won't
work...

Can someone help?

I submitted the error message in a .jpeg file
