S3 Media Maestro conflict with W3 Total Cache

S3 Media Maestro and W3 Total Cache both use the AWS SDK, which can cause a conflict. You can fix it by telling W3 Total Cache not to load its copy of the SDK. Add this line to your wp-config.php file, above the line /* That's all, stop editing! */:

define( 'W3TC_SKIPLIB_AWS', true );
