Some times when I try to change the width of columns or regions with Fluid Width the panels displays the NAN% and it doesn't change the width

enter image description here

Using Firebug I got the following error

enter image description here

What should I do?


It only displays this javascript error in console in flexible-admin.js file

splitter.parent.css('padding-right', (splitter.right_padding + moved) + 'px'); 
  • You might want to include the error as text so people can find it via search engines.
