I came across a strange behavior, I developed a site and its certificates (with images) in a development server, there all works fine, we can generate a template, relocate the elements and the PDF is generated just fine.
OK when I upload the moddle to the production server, in the administration i can still view the images and i can relocate them but none of the images uploaded in the dev server are included in the PDF, but if I upload a new image in the production server this image is included in the PDF jus fine.
All the images (those uploaded in the dev server and the new ones) are stored in moodle_data correctly I check the hash width sha1sum and check the files table in the database too.
I'm using Custom certificate 3.8.2.
Thanks in advance!!
