I updated to Ubuntu 14.04.1 and now I can't get into Grub Customizer.
I am getting the following errors:

chroot '/media/grub-customizer_recovery_root_mountpoint' grub-mkconfig couldn't be executed successfully. error message:

Any ideas or help?

Im not familiar with grub customizr, but i assume it will call the underlying scripts, namely grub-mkconfig which might fail here.

Run the debug command from here Debian Bug 736928

sudo sh -x /usr/sbin/grub-mkconfig >/dev/null 2>grub-mkconfig.err

and look at grub-mkconfig.err, which showed me what the problem was for me, a customized 00_header file which was not valid anymore.

You might also be facing a problem where GRUB is installed into /boot/grub/i386-pc but the GRUB_PREFIX variable isnt set anywhere, just like mentioned here.

Fix this by making a backup of /usr/sbin/grub-mkconfig and add the following lines at the top, where the other variables are set

GRUB_PREFIX="/boot/grub/i386-pc"
export GRUB_PREFIX

You might just set the variable somewhere else, thats up to you.
