Thank you for your help. I tried following that guide, but with no success. The changes I am making in my member-header file in my child theme are not being reflected on my site. I even went as far as deleting everything in the file and typing “abc” just to see what happens. Nothing changed.
I was careful in copying the directory over in my child theme, but it just doesn’t seem to be overriding the default file.
I needed to copy the bp-legacy directory, not the bp-default directory, correct?
