The image from the enrolment email is missing. It does exist for the registration email but for some reason it is not there when enrolling student in a course.
Ok so I figured out how to fix this…
in youtrheme/lms/templates/ace_common/edx_ace/common place
base_body.html and return_to_course_cta.html
then run tutor images build openedx;tutor local stop;tutor local start -d
and that will fix it
