Hi Mizuho,
I’m using PHP v5.6.24. And I can only select “imageMagick with exec”.
Thank you for updating. I’ve updated and turned on WP Debug, but the only error I got was:
Warning: Cannot modify header information – headers already sent by (output started at …/wp-includes/functions.php:3995) in …/beta/wp-admin/async-upload.php on line 35
1106
And this error also comes with a normal JPG file upload.
It still only creates thumbnails from CMYK PDFs, not from RGB PDFs. And the CMYK thumbnails are still in CMYK.
What can else can we do?
Regards,
Holger.
