How to Fix Username & Password Prompt Issue in Flash
At work, we came across this issue with Adobe Flash CS4 that had to do with username and password prompts. You might recall this. You’ve added your swf to a live site, then you are prompted by a username and password box.
Annoying right? Funnily enough, the solution is quite simple:
[success]SOLUTION: re-publish your swf and re-upload[/success]
If that fails, re-publish your swf from another computer.
[notice]Update (SEP 2011): It looks like we had people using different versions of Flash. Some were using CS4, while others were using CS5. Publishing from CS4 seemed to do the job.[/notice]
