Thanks for the help. Just a note, I ended up getting this fixed myself. In case anyone else runs into this, I moved the wpml-config.xml file into the child theme root directory. Then changed the code to (I changed the < tags to ( so they would not be stripped out):
(key name=‘custom_logo’ /)
Essentially the ‘site_logo’ needed to be custom_logo and the file location is incorrect, it needs to be placed in the child theme folder not a new polylang folder. I had tried custom_logo but not moving the file into the child theme folder.
Thanks again, I really appreciate your effort in trying to assist Roman.
