An invalid or illegal string was specified" code: "12
After thinking about it for a little, I chose to revert my doc type to Xhtml 1.0 Strict.
Oooh! I can’t wait to see the new layout for NM! 🙂
Hi, I was searching the web for above problem that’s triggers from js; “An invalid or illegal string was specified” code: “12” and found the solution. Its because ID-tags attributes used are only numeric, so change them to use a-z before eg. a123 or a_123. This problem suddenly occurred for me using latest browser versions, they probably have more strict xhtml policy.
