Is the errant PHP 8.1 GD compiled with GIF Read & Create and PNG support?
I don't know about that, server is hosting provider, but since one website working with should be.
I just reinstall virtue mart on non working website and still don't work, (is still in testing mode this website I have just some test categories and products) I enable debug and everything and when I try create new product I get
An error has occurred.
0 Undefined constant "IMG_GIF"
and
administrator template new and old template CSS is broken.
I change to PHP 8.0 all working OK
It was working with php 8.1 til 2 hour ago, when I upload first picture .png in to some of test product, I save and close. But when I enter product I get this error.
Now with reinstalled virtue mart no product no pictures nothing, when I create new product I get this error always.
