Hello,
Is all the info at this link still relevant to version 3?
http://www.seblod.com/v2/documentation/seblod-2x/templates/2754-getting-started-with-custom-templates-positions.html
EG: At the link, this text can be read:
"Make one copy of the “right-a.php” file for every position you are using
in your Seblod content type, and place these files inside each of the
sub-folders mentioned above."
I don't see a 'right-a.php' file in the templates/seb_one anywhere....
