Request Entity Too Large

Sometime between 2 days and today, a new error has appeared when I use the admin panel to upload media. The upload fails and the information that appears over the image looks like this:


I have checked the php upload limits and the upload limit in system.yaml, and my files are well below these values. Also it makes now sense that this was working a couple of days ago and now it doesn’t. I’ve also tried different browsers and reinstalling the admin plugin.

This occurs for all files over 1MB in size. Under 1MB seems to be fine.

Anyone have any ideas?

I faced same problem and solved!
