Hello Neil, Yes, I think that your assumption about PATH can be correct. It looks that the /usr/local/bin path is not accessible for executing by PHP exec().
If you want you can add at the beginning of the mtx-changer script echo $PATH to see where exactly mtx-changer looks for binaries when it is executed via web. I found that FreeBSD users report this problem with PATH too: https://forums.freebsd.org/threads/heads-up-php-exec-does-not-look-in-usr-local-bin-for-executables.78098/ Fortunately it is not difficult to solve. You can fix the PATH in mtx-changer script or globally if it is possible.
