Image Upload HTTP error Wordpress


Staff member
When I upload the image in the wordpress,I get the HTTP error.Though images are inserted in upload folder.Yet it shows the error.

I have tried with the .htaccess work
SecFilterEngine Off
SecFilterScanPOST Off
but didnt work.I also tried with permission for the uploads folder issue.
I dont have any error in the debug.log just few of the PHP Notice
I have wordpress 3.3,windows with the apache server.
