The first thing to do would be to make sure that the path to imagemagick is correct by using shell access to try and run convert yourself. It's the only (quick & easy) way to positively identify if the path is okay. If it is correct then yes for some reason the resizing isn't working. If your servers imagemagick is below version 6 the carrot (^) flag for square cropping thumbnails will not work, but that shouldn't stop it from at least creating non square cropped thumbnails.

Does this mean that the scripting IS able to reach imagemagick, but for some reason the resizing isn't working? Nope the thumbnails indeed do not exist; i.e. the uploaded image isn’t being resized.

Does this mean that the scripting IS able to reach imagemagick, but for some reason the resizing isn’t working?

It looks as if it's trying to find the resized images & can't which would mean (to me at least) that Imagemagick isn't creating thumbnails. Check to see if the image files that the previous errors gave you exist as Imagemagick doesn't return errors if it can't resize images, it just continues on with the script.

“While yes, this is beyond our scope of support, I would suggest updating the part of the script that generates the file name for that function. You may want to replace that with this PHP variable (depending on how it works):

$_SERVER["DOCUMENT_ROOT"]
