Hi DongZheng,

You can disable the flash uplod mode by the steps below, then the user will not get this problem anymore.

1. open file phpuploader\include_phpuploader.php


2. find section below


$code.=$this->_GenerateAttribute("ProgressBarBorderStyle");


3. Change it to


$code.=$this->_GenerateAttribute("ProgressBarBorderStyle");
$code.=" AdvancedOptionNoFlash='true' ";

Regards,

Ken
