May be a memory issue...
in the admin section click on tools, then sytem..
What's the php memory-limit number?
You can up it as follows....
Check the folder conf and the file advanced.php...

// If you get blank pages, PHP may be crashing because it doesn't have enough memory.
// The default is 8 MB (in PHP < 5.2) and 128 MB (in PHP > 5.2)
// Try uncommmenting the following line:
// ini_set( 'memory_limit', '32M' );

I went into admin and found:

PHP upload_max_filesize
32M
PHP post_max_size
32M
post_max_size should be larger than upload_max_filesize
PHP memory_limit
32M
