The forum integration tab in the user profile tries to retrieve the user's Rank image from the default template, regardless of which template is actually being used by Kunena.
Code:
[error] File does not exist: /components/com_kunena/template/default/images/ranks/f40.png, referer: http://www.friendlyphotozone.com/index.php?option=com_comprofiler&task=userProfile&user=71
should be referring to
Code:
/components/com_kunena/template/$current-template/images/ranks/f40.png
instead.
