Upload error 500 when using flash to upload

I've been trying to configure uploading and I've been getting an error 500.

I'm running a server on Apache2 with php5+ installed. I'm curious to why i keep getting an error.

I added these commands to try to fix it, nothing has worked yet.

  <IfModule mod_s开发者_如何学运维ecurity.c>
    secfilterengine off
   secfilterscanPOST off
</IfModule>

<ifmodule mod_php5.c>
 php_value upload_max_filesize 1000M
 php_value post_max_size 1000M
</ifmodule>

I looked at another solution but i don't know the module command for it,

SecRuleEngine Off

SecRequestBodyAccess Off

NOTE: I added those to my .htaccess file

a 500 should put something useful in your /var/log/apache2/error.log
