# IO Error using Flash Uploader

 * This seems to be a common issue with WordPress, but when I try to upload images
   using the Flash uploader I get the dreaded red **IO Error**. I’m using the most
   recent versions of Firefox, WordPress and Flash.
 * Some online forums suggest using the browser uploader, but I need to be able 
   to upload multiple images at a time (which is apparently impossible unless you
   use the Flash uploader). **I can successfully upload when I try on my wife’s 
   computer, suggesting it’s not a WordPress-based issue.**
 * I cannot currently use other browsers (Safari, Chrome, Internet Explorer). I 
   haven’t changed my proxy settings at any point. Could certain flash-based programs
   be conflicting which is causing the error?
 * I’ve tried installing, re-installing, downgrading, upgrading and restarting but
   to no avail. **This is driving me crazy.** Somebody, anybody… HELP!

 * Thanks Esmi, but I’ve already tried uninstalling and reinstalling several times.
   I don’t know if that’s the problem. I also cannot uninstall/reinstall Java…
 * Uploading with Flash works on my wife’s computer but not on my home laptop or
   office PC.

 * Sorry but this is obviously not a WordPress issue but a problem with your local
   machines.

 * At work it could be the firewalls they have (It never works for me at the office).
 * At home, it could be a hundred things, but it boils down to your laptop. It could
   be the operating system, the browser, conflict with other apps…
 * Try Chrome, by the way. It has its own Flash included.

 * Hmm, I can’t get online with Chrome or Internet Explorer. Just Firefox.

 * Then you have some pretty serious problems with that computer and I’d take it
   to get fixed.

 * Sounds like Chrome and IE may have proxy settings that Firefox doesn’t (Chrome
   uses IE/system proxy settings). Might want to check that.
