I know it's been a while since this thread started and it appears that this is working for people...except me. I just started with SS a few weeks ago and I know I have the latest versions of SWFupload. I've also tried the various .htaccess entries that are listed here but...I'm still getting this error whenever I try to upload larger MP3 files.
I'm trying to upload MP3s to a Podcast module. At first I got the error that the file was too big and it had to be under 20MB. I reduced one file to 17.5MB and it goes through uploading the entire file right up to the last second then errors out.
I did change the _config.php file to accept larger files but that's still giving me the 20MB limit error as well. Any suggestions? I use 1and1.com to host my site.
