I'd like to know where DMS writes custom CSS/LESS & Custom Scripts.  
 
The reason I ask, yesterday I inadvertently pasted the wrong script into the custom script area I got a white screen. Neither the wordpress side or the pagelines side were available.  
 
I've since resolved the issue by restoring the site with its last backup. I'd like to know so next time I could FTP in and delete the bad code.
