Thread:Project:Support desk/Upload not functioning, no error messages/reply

I have exactly this issue myself with an internally used system (details below)

MediaWiki 	1.16.0 PHP 	5.2.4-2ubuntu5.17 (apache2handler) MySQL 	5.0.51a-3ubuntu5.8

I've looked at folder permissions, it loads a similar file of the same type (I'm uploading a .zip file). I suspect it's some size related thing (the file is 9Mb whereas my test zip file is smaller). I extended the allowed file size in LocalSettings.php and php.ini and restarted Apache but although the upload page now showing 100MB it still doesn't change the response (wasn't sure if the Mb vs MB distinction is being made here, ie megabits of megabytes, so I whacked it up to a vastly bigger limit). I also added the allowed types to include the two file types within the zip to cover the unlikely event that it somehow looks inside (I don't think it's that sophisticated, but I haven't done that deep an investigation into the code)

Does anyone know where we could look to see any logging of what's going on? Presumably that might indicate a specific cause for the failure.

Many thanks, Neil
