I was trying to think really hard if any proxies got changed, and I realized that I did move to Cloudflare recently in the last week or so.
The error:
0033.641 (0) PHP event: code E_NOTICE: Undefined property: stdClass::$body (line 2169, wp-content/plugins/updraftplus/includes/S3.php)
Is it possible to make these two play nice? I'm guessing that it's because of Cloudflare, because updraft has been working fine for months now.
Thank you for your support and patience.
