I added the code to the top of
but it made no difference so i deleted the code I contacted the hoster who tells me that the upload limit onn their shared platform is 20mb and is cannot be changed.
I then created zip files
2,3,4,6,8,10,15 and 19mb in size
2 3 and 4 are uploaded ok but anything larger fails the progress bar dissapears in around 15 secs but I am on 40mb broadband
