i am using the default template... I've never change it...
i don't know what happened but when i open
menu ->
edit html template 
i just click on the
restore default and hit
ok - than everything is normal without warnings...
maybe after so much updates something went wrong in the source of the template...
now everything is ok... thanks for the advice...

and just wanna say that i appreciate what you doing man...
