When I try to edit a profile with the old Jomsocial version I do get the error "Class only available on Joomla 1.6". (I have 3.8).
I know there is already a thread for this subject: https://www.jomsocial.com/forum/profile-universal-features/37482-solved-joomla-3-8-and-class-only-available-on-joomla-1-6-issue but, I do not see the attachment file. I am logged in and only see the message "This message has an attachment file. Please log in or register to see it.".
Can you please help me out with the file? I know the best would be to update Jomsocial. I did this already on a testserver but it caused some problems which I would like to discuss in a seperate thread.
