# “Missing required client configuration options”

 * I’m creating my own support topic since I’m not getting a reply here:
    [https://wordpress.org/support/topic/s3-api-error/](https://wordpress.org/support/topic/s3-api-error/)
 * We’ve had BWPup running without issues for a long time on two of our 100+ sites,
   but just in the last week, got this error message. Any idea what’s causing this?(
   Just FYI: our other 100+ sites on the same server, sending backups to the same
   S3 account, using almost identical settings are NOT giving this error — at least
   not yet.)
 * `ERROR: S3 Service API: Missing required client configuration options: version:(
   string) A "version" configuration value is required. Specifying a version constraint
   ensures that your code will not be affected by a breaking change made to the 
   service. For example, when using Amazon S3, you can lock your API version to "
   2006-03-01". Your build of the SDK has the following version(s) of "s3": * "2006-
   03-01" You may provide "latest" to the "version" configuration value to utilize
   the most recent available API version that your client's API provider can find.
   Note: Using 'latest' in a production application is not recommended. A list of
   available API versions can be found on each client's API documentation page: 
   http://docs.aws.amazon.com/aws-sdk-php/v3/api/index.html. If you are unable to
   load a specific API version, then you may need to update your copy of the SDK.`
 * I wondered if the issue was caused by a specific S3 key pair, but no — happens
   with other key pairs.
 * The error also appears on the S3 tab of the backup job, under “Bucket selection”
 * Just as a test for any corrupt files (since this is only happening on ONE of 
   our 100+ sites), I totally deleted the plugin via FTP and re-uploaded a fresh
   download. Same error.
 * Can you point me toward how to get this resolved?

 * Hi [@bethannon1](https://wordpress.org/support/users/bethannon1/),
    Sorry to 
   hear that you are facing this problem, could you please test our private beta
   plugin by dropping us an email to [support@backwpup.com](https://wordpress.org/support/topic/missing-required-client-configuration-options/support@backwpup.com?output_format=md)?
   Thanks!

 * This turned out to be a problem with S3 Media Maestro. They had fixed the problem,
   but a licensing snafu kept my sites from being updated. Once I updated to the
   current version of Media Maestro, the problem went away.
 * If anyone else is having this problem, I would encourage checking for plugin 
   conflicts. Because the problem seems to be only between BackWPup and Amazon S3,
   I never thought to check for plug-in conflicts.
