I have 2 mp3 files with sizes 24.7kb and 11mb.
When I try to upload the smaller file, I get no errors.
When I try to upload the bigger file, I get an error. In firebug, I see something like
NetworkError: 404 Not Found - http://domain.com/application/form/%3C!DOCTYPE%20HTML%3E%3C!--%5Bif....
After checking and parsing the string after "form/", it seemed to be the markup of the webpage you are on.
Any idea why this happens?
P.S.
I have checked my PHP.ini and Expression Engine's file upload preferences and made sure that my maximum file size limit is more than 10mb(used 20mb).
I am using ExpressionEngine for my framework and Safecracker for my forms
On Mac, it seems the markup string is shown somewhere in the DOM and you can see it in the page. I don't see it in Firefox or Chrome though
This is probably still a server issue, rather than something EE specific. I would start by checking the following settings in php.ini (in addition to upload_max_filesize which it sounds like you've already bumped up, in roughly the following order:
max_execution_time sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. I think the most likely candidate is this one, as it's quite possible that this is being exceeded during the upload or post-upload processing. Default in PHP 5.3 is "30"
post_max_size (must be greater than upload_max_filesize). Sets max size of post data allowed and also affects file uploads. Default in PHP 5.3 is "128M" but some hosts reduce it considerably.
memory_limit sets the maximum amount of memory in bytes that a script is allowed to allocate. Unlikely to be this one as you'd almost certainly get a PHP error instead, but worth a check for completeness. Default in PHP 5.3 in is "8M"
