(SOLVED) Javascript widgets not working anymore in Safari (multipleDefine l@

We have a problem in Safari. All java script widgets give the error: ‘No Constructor Found for widget ….’ Sometimes it seems to work but when I refresh the page we get this error in de log and console: multipleDefine l@ Xe@ c@ Je@ r@ and Loading module failed! Check console log for more detailed debug information. I already downloaded en overwrited all java script widgets from the app store. Thanks for you help.

Problem solved: I replaced the index.html with a clean index.html. 
I think I adjusted the index.html to much with javascript things.
