Upload failures

Seeing File Up failures with files approximately 2MB or larger. Configured max size in the plugin is 16MB. Server is configured for a maximum post\upload size of 32MB. Observed so far on both Safari and Chrome.

The failure results with the message “Sorry about that, but <filename> could not be uploaded”. I turned on debugging and observed an error of “Undefined index: nonce in …/wp-content/plugins/file-away/lib/cls/class.fileaway_management.php on line 23”. I then added some further debugging to that section of the code and observed that when the failure occurs, only the ‘upload_nonce’ field is present in the POST array (a success shows all POST fields). Looking at management.js line 1507 on, I see that ‘upload_nonce’ is the first field and that the second is the file itself, so it seems to me that something like a 2MB limit is being imposed, so that the rest of the POST array is being discarded. The ‘nonce’ field is then not present in the received data, causing the observed error. Does this seem correct, or do you see other possible explanations?

Any ideas on why a 2MB limit would be imposed despite all settings appearing correct in the PHP configuration? I’m raising this with my web host in parallel, but wanted to see if you had any insight. Thanks.
