Title: S3 API Error Last modified: August 21, 2017 --- # S3 API Error * Resolved [a2adv](https://wordpress.org/support/users/a2adv/) * (@a2adv) * [8 years, 7 months ago](https://wordpress.org/support/topic/s3-api-error/) * We are using your plugin thru MainWP. We are trying to backup to AWS S3. I opened the S3 permissions up fully to test and I am still getting the following error message. It looks like this is running an older version of the api. * 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](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. * Thank You Mike Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Author [Alex Frison](https://wordpress.org/support/users/seville76/) * (@seville76) * [8 years, 7 months ago](https://wordpress.org/support/topic/s3-api-error/#post-9450849) * Hey [@a2adv](https://wordpress.org/support/users/a2adv/) we still working on it. We will let you know the next coming days. * Moderator [Bet Hannon](https://wordpress.org/support/users/bethannon1/) * (@bethannon1) * [8 years, 5 months ago](https://wordpress.org/support/topic/s3-api-error/#post-9645112) * We’ve had BWPup running without issues for a long time on one of our sites, but just last night, got this same error message. Any update on what’s causing this?( Just FYI: our other 100+ sites on the same server, 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.

Same error. - This reply was modified 8 years, 5 months ago by [Bet Hannon](https://wordpress.org/support/users/bethannon1/). * Moderator [Bet Hannon](https://wordpress.org/support/users/bethannon1/) * (@bethannon1) * [8 years, 5 months ago](https://wordpress.org/support/topic/s3-api-error/#post-9651569) * a2adv, * Did you get this solved? * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [8 years ago](https://wordpress.org/support/topic/s3-api-error/#post-10149694) * [@a2adv](https://wordpress.org/support/users/a2adv/) since this has not been responded to in a while, I’m going to mark it as resolved.
