Error message uploading files

Permalink
I've uploaded files before to my site, but today I'm getting this error message for any upload I attempt:

Upload Failed
Declaration of Carbon\Carbon::setTime($hour, $minute, $second = 0) should be compatible with DateTime::setTime($hour, $minute, $second = NULL, $microseconds = NULL)

I've tried JPG, PDF, etc. Nothing uploads. What does this mean? How do I fix it so I can upload files again?

Thanks!

Has your version of PHP been changed by our hosting provider?
