File Manager File Upload

I just upgraded to EVO 1.0.4 over the weekend and my file upload function will no long upload over 2 MB in size. It does upload anything under 2 MB, so it is not a permissions issue.


IN TOOLS > CONFIGURATION > FILE MANAGER (TAB)

I have my Maximum file size set to 73400320 Bytes 70 MB.

In my PHP.ini, I have the following setting

; Maximum allowed size for uploaded files.
upload_max_filesize = 70M

; Maximum size of POST data that PHP will accept.
post_max_size = 85M

Using Fiddler to view what is going on, I get the following error message.

HTTP/1.1 413 Request Entity Too Large

I am running MODX on Windows Web Server 2003 with IIS 6.0

I have ISAPI REWRITE installed for my Friendly URL redirection.

Can anyone advise.

The upload was working with files larger than 2 MB in EVO 0.9.6

Thanks
