Some people have reported the “Choose files to upload” button being broken when trying to add an image to a WordPress post. The behavior I witnessed was that clicking the button simply did nothing. I have also heard that PC users see a blank white window. The quick fix is to use the Browser Uploader instead.

We’ve noticed the issue since upgrading to Flash 10. It seems the deadly combination to break the WordPress image uploader is WP 2.6 (and maybe lower) and Flash 10. Sites that have been upgraded to WordPress 2.7+ work just fine with Flash 10. See my previous post, What version of Flash Player do I have? to check yourself before you wreck yourself.

Big thanks to web guru @joeyyax for sussing this one out, and for pointing out this this thread at WordPress.org.

Some sites will tell you that you need to upgrade your Flash player to see their content. Don’t always believe it. Check your Flash Player version, and compare it to the latest Flash Player version here: http://tinyurl.com/yrlrvb. Sometimes, the developer makes an assumption about which browser or operating system you might be using. If you don’t match that assumption, they will toss you the “upgrade your Flash Player version” error. Don’t believe the hype!
