thrown in /www/wp-content/plugins/gp-premium/library/image-processing-queue/includes/class-ipq-process.php on line 71
[11-Oct-2018 23:34:07 UTC] PHP Fatal error: Uncaught IPQ_Process_Exception: Unable to get WP_Image_Editor for file “/www/wp-content/uploads/2009/07/P7230386.JPG”: File doesn’t exist? (is GD or ImageMagick installed?) in /www/wp-content/plugins/gp-premium/library/image-processing-queue/includes/class-ipq-process.php:71
I use Flywheel is there something missing?
