I am having problems with functions that manipulate JPEG images, I went to see in phpinfo () and the incomplete GD, according to some information I got. You can see my php in the GD part that is missing the JPEG option.
Without this full library is not working, the imagecreatefromjpeg () function of PHP and I can’t generate thumbs.
The problem happened after doing an EE version upgrade.
