Hi Wayne,
I still can't access your back-end
. Fortunately, I can access your ftp
. I've searched your language directory (JoomlaFolder\administrator\language\en-GB\en-GB.plg_app_group_blog.ini) and it seems that you are missing the en-GB.plg_app_group_blog.ini file.
I've uploaded the file to your ftp. But because I can't access your website, I can't check it. So can you try and see if the problem still persists?
