Fixing request entity too large error under django/apache/mod_wsgi for file uploads
That would indicate that you have LimitRequestBody directive set to a very small value in the Apache configuration. This directive wouldn't normally be set at all if using standard Apache. Even if you happen to be using mod_wsgi-express the default there is 10MB. So it must have been overridden to a smaller value.
I after much gnashing of teeth found out my uploads were working just that I was getting a request entity to large 413 error I wasn't seeing.  The django app is running under apache mod_wsgi, and I am no apache guru so i am not sure what I need to set to handle larger files.  I tried to google online but it was unclear if it was a timeout issue or a file size restriction issue to me.  Also not clear if it is a setting in my settings.py file.   I currently cannot upload anything over 1MB about.  (Doesn't even sound right for all the defaults I read)  Anyone done this before and can give some insight?
