"Unable to create new image" WordPress

Question

This problem looks like it's not had a clear solution as yet. I have installed a clean version of WordPress via SSH with folder permissions set to 755 and file permissions to 644.

I have no problem uploading images, updated plugins etc, but when it comes to editing an image I receive this error:

WP_DEBUG shows nothing, and there are no other errors on the website.

Answer 1

The most likely reason is not having mod-gd installed.

WordPress uses the GD Graphic Library to manipulate images (see wp-admin/includes/image.php ), and this error appears when it is not installed.

It can also be caused by whitespace introduced somewhere. Check for any php closing tags ?> and remove them. They should not be used because whitespace can be introduced after them.

Answer 2

同样的问题，我忘了用 php 安装 gd ......安装它解决问题：

sudo apt install php7.2-gd

Answer 3

It happened to me when I tried to restore image after scaling and the max size was below the original image size. I couldn't change max size but found copy of my image on google and just replaced it.
