sempress_enhanced_image_navigation breaks media library

[christopheranderton]

The section with sempress_enhanced_image_navigation( $url ) (Line 555 to 565 functions.php) breaks the media uploader in WordPress 3.6-beta1-24041 (no plugins).

Uploading images will return "An Error Occurred In The Upload. Please Try Again Later". The media library will also not show any media.

Commenting out the section will get media library and media upload working.

The issue does not occur when Twenty Thirteen is activated.

Thanks a lot! I had the same problem for weeks http://wordpress.org/support/topic/cannot-upload-images-to-posts-1?replies=14 but I couldn't find the cause! The strange thing about that... It only happens with WP_DEBUG = true... But it should be fixed now.
