Because your PHP version is really outdated and will not receive any security fix or performance improvement, you can check here: [https://www.php.net/supported-versions.php](https://www.php.net/supported-versions.php) And I know that the reason to not upgrade the PHP version may because of code compatibility, but I think, at least you can safely upgrade the PHP version to 5.5 or much better, 5.6 * Thread Starter [cyberdark](https://wordpress.org/support/users/cyberdark/) * (@cyberdark) * [6 years, 9 months ago](https://wordpress.org/support/topic/aws-sdk-incompatibility/#post-11760332) * Hi, hello, not possible in my case. * I’d suggest you then to update the plugin PHP minimum version on [https://wordpress.org/plugins/backwpup/](https://wordpress.org/plugins/backwpup/) * Thanks a lot for your help! * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [6 years, 9 months ago](https://wordpress.org/support/topic/aws-sdk-incompatibility/#post-11760372) * Hi [@cyberdark](https://wordpress.org/support/users/cyberdark/) Thank you for noticing it, I already request PHP minimum version update to our plugin release manager ^^ So it expected it will be updated tomorrow.
