I'm writing a web application in GWT and always worked in Dev Mode. I wanted to check some things in other browsers so I compiled the whole app and opened it in all major browsers. The application shows in Firefox and IE, but not in Chrome and Safari. Chrome and Safari just give me a blank page. When I press ctrl + u to view the source, the code is there, but it doesn't to anything.
I already checked the html host page for errors with the W3C validator but there were none. Any other suggestions?
