problems adding a link online, but not offline

hi, when i try to add a link with the ckeditor my links becomse like this:

mydomainname\"the_real_url\"

but when i work offline , on my XAMPP server everything works fine, i have no idea how to fix this and why this problem occurs.

i havent really done anything. I just downloaded the ckeditor folder and first uploaded it on my XAMPP server to work offline, and test it there. And then i just changed the style , and limited the buttons on the editor. Still it works great offline, but when i upload the editor to my website online, it just keeps adding

mydomainname\"the_real_url\" to ALL my urls..
