Hi,
From this page:
https://www.gavick.com/updates/templates/gk_corporate2,745.html
This page gives many files to update.
I went through each of them and updated them.
I believe there are mistakes on the page:
I was told to update css/gk_stuff.css, but there is no such file. (In fact, this non-existent file is listed twice.)
There IS, however, a css/gk.stuff.css that can be updated.
I was also told to update en-GB.tpl_gk_postnote.ini
There is no file of that name. I suppose the file that needs to be updated is:
language/en-GB.tpl_gk_corporate2.ini
Are these the correct files and actions? If so, you might want to change the page to the correct instructions.
