keep getting upload php $_FILES error = 3 (partially uploaded)

Question

I am using dropzone extension for Yii framework to upload some files by registered users. Everything working well but some users for some files that they trying to upload it

Answer 1

in my case, the "partially uploaded" problem happened when uploading medium/large files using a slow internet connection.

The solution that works for me was set some Apache configurations in httpd.conf file:

TimeOut 300
KeepAliveTimeout 10
RequestReadTimeout handshake=0 header=20-1200,MinRate=200 body=20,MinRate=200

I hope it help.
