Can't upload files over 10mb

I have been searching on this issue for days and nothing. I have installed the latest Owncloud on my web hosting, and use Mac OS Sierra to upload files with the owncloud app.
I have files over 10mb that won't upload while I have other programs on the server uploading without any issue files up to 500mb. I deduced the issue comes from owncloud and I cannot figure out from where. I found an article mentioning to change the "chunksize" variable from owncloud.cfg but there is no such option in my file on my mac.
Has anyone figured this out?
