Can't upgrade. Don't have a test website to unistall/reinstall and don't want to do that directly on main site so it wouldn't mess everything up as I got a lot of hacks. I need help :) Thanks!

Hi Islam,

this is not jomsocial issue. as you can see at error message, that mod_topmember already exist. please delete it first. file manager not 100% perfect. you can use FTP client.

Can you give me exact steps please? What and where exactly?

Hi Islam

you can googling for it:
wiki.filezilla-project.org/FileZilla_Client_Tutorial_%28en%29
www.siteground.com/tutorials/ftp/filezilla.htm

jomsocial only provide support for jomsocial issue.
