Sorry i don't know if it's stupid question but...

When i try to upload my .zip file with my .capx progect there are this error:

<font color=red>"Zip contains file extensions not on the whitelist"</font>

I've read all whitelist with all Supported Plugins and Behaviors but for mine progect it's ok.

i've this Plugins and Behaviors:

<font color=blue>Plugins</font>: Audio, Mouse, Sprite, Text

<font color=blue>Behaviors</font>: Bullet, Fade

Only it!

And the Maximum width of the game is 800px and the the largest sprite is 800, 800

I use only HTML 5 and no one Plugins, the file is < 10mb

I don't know... Sorry but can help me? <img src="smileys/smiley19.gif" border="0" align="middle" />

Did you export your project and select 'scirra arcade' in the export options?

No, i hope it's the problem, How i can do it?

Follow this tutorial.

Also about the maximum width, it is the width of your project that must be 800 max, not the size of your sprites.

I wrote it for 1536, 2048 ... now I'll have to resize everything to upload?

It throws error "extension not in whitelist"

All plugins look okay.. can having larger game width throw the same extension!
