Cannot upload picture concrete5 18.104.22.168 PHP7.1
I want to try an old concrete5 22.214.171.124 with PHP7.1 to test how the element "slideshow" is called in this version.
To try out the slideshow block I have to upload an picture, but it is not possible because I get this error during upload:
pic.jpg Declaration of Carbon\Carbon::setTime($hour, $minute, $second = 0) should be compatible with DateTime::setTime($hour, $minute, $second = NULL, $microseconds = NULL)
Maybe wrong PHP version?
Where can I find out which version is necessary for 126.96.36.199?
