Thank you LSRN94
Worked for me
As for me, I downloaded the latest version of Flash player and all things turn out fine.
This worked for me
After a bit of troubleshooting, adding this to the .htaccess file in my WP root worked:
<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>Turns mod_sec off on the async-upload.php file.
Thanks LSRn94
found a plugin for this error that will fix in less than 5minutes shows video if you need to watch go to http://www.learnaniche.com/cool-tools
This fixed it for me:
* Enter absolute path to uploads directory (in Settings - Miscellaneous section)
* Uncheck "Organize my uploads..." check box
Hope this works for others!

Another possible cause and solution to this problem is the client_max_body_size in the NGINX web server config. I'm running WEMP (Windows, Nginx web server, MySQL, and PHP) on a Vista system and this was the cause of my problem. My original problem was the PHP limit, which I corrected under max_upload and max_post in php.ini. However, after that I was getting an error where it would freeze at "crunching" for any file over 1MB. Nginx places a 1MB limit on all uploads by default and this has to be over-ridden in the Server section of nginx.conf. Insert the line "client_max_body_size 20M;" (don't forget the semicolon at the end) just under the server_name entry, or anywhere in the server section, and it might help you out. It didn't work for me if it was nested in the location section.
Good luck!
