User can create folders but cant upload to share

No, its ticked off in the admin settings.

My data folder is here-

/mnt/sftp/owncloud

I had to change owner -

Chown -R apache:apache /mnt/sftp/owncloud

When i opened the web gui for the first time ie setup it asked me where i wanted the data folder.

My web pages are here -

/var/www/html/owncloud

i have installed this on a centos 7 machine

ok good im getting somewhere at last...

my user who i have shared the folder to via the admin account can upload some files like .jpg/.txt/.sh small files but .iso/.zip ie big files i cant

also whats wierd is that my user cant delete the files i have uploaded, even tho my user has got the deleted tick box ticked
