Cannot save modified style in CSL editor?

Hi, Does anyone else get the error "Uncaught TypeError: Cannot read property 'url' of null url: http://csl.mendeley.com/src/visualEditorPage.js?bust=1f2636391c0e67f05371370ac3cd57294c74739d line: 443" when attempting to save a modified style in the CSL editor? If so, are there any fixes? Need to save a modified style for my thesis. I'm using the Chrome browser.
