Server 500 with no extra info

@mpociot

Sorry I appear to be making your website crash with a 500 error and no further information.

I'm attempting to send a 24.5meg file for translation but it crashes out with no error logs.

I'm more than happy to pass on extra information/the file if you need any for debuging. Apologies if it caused any issues for yourself.

Start by reproducing a translation upload with a 24.5 MB file and inspect the server error logs, since the report says the request returns 500 with no logged error. Done means the upload no longer fails silently, or the failure produces enough diagnostic information to identify the cause.
