Upload Error 503 when uploading using flash file upload

[yfrigi]

Hello everyone.  I'm having issues when uploading on my Coppermine driven gallery http://mikolji.com/galleries/
When using http uploads and the suggested settings for upload troubleshooting in place,the file uploads without any errors.  It' only when using the flash file upload that I get the following:

Upload Error: 403.

I've gone through the upload troubleshooting instructions. I've changed the permission settings in /albums, /albums/userpics and /albums/edit to 777.  Can someone please help?

I've setup debug mode.
Here's the test user account data:
    Username: tester
    Password: tester

I have been using the image taken from http://mikolji.com/IMAGE_GALLERY_PORTFOLIOS_IVAN_MIKOLJI_PIRANHAS_DSC00467.html as an example to test with.

I don't know what to do next.
Thanks in advance for your suggestions!

I called my hosting company and they added an .htaccess file in my CPM root directory with the following:

1 <IfModule mod_security.c>
  2     SecFilterEngine Off
  3 </IfModule>
  4
and gave my userid permissions and now it works.
