Have you made other modifications to your class.report.php file? Your line 192 is not the same as my line 192, or the same as line 192 from a fresh download.Also, you might want to try downgrading your PHP from version 7.1 to 5.6. Your initial post said you were running 5.6 but your screen shot says otherwise.In my screen shot, the left side is from the 1.10.1 download zip and the right side is my modified file.
