class.upload.php is a powerful and mature PHP class to manage uploaded files, and manipulate images in many ways. The script is available under a GPL license.
more info about the class
In my sites i used the upload-class which works really fine. But now i moved a site to another hosting. When uploading an image, i got this message :
Notice: Use of undefined constant IMG_WEBP - assumed 'IMG_WEBP' in /home/0013/sites/domain.com/web/extern/class.upload.php on line 2169
I dont know why i got this error-code now. Anyone who knows why i got this message and how i can fix it?
Thnx,
Best regards,
Rene
