GetSimple and Adobe Flash Player

[cuirassier]

Flash was only needed for file upload. It is not necessary, you can use uploadify instead.
In the gsconfig.php file, uncomment this line:
#define('GSNOUPLOADIFY', 1);

There are even alternatives for uploadify like this plugin:

It works!
Thank you very much!
