Hi, BS BLOG 01 doesn't use featurebox plugin at all.
It uses theme shortcodes on homepage:
and it uses this: (parameters are hardcoded)
You can have the same result by using news_grid menu directly from admin/menu manager. Just select the same limit, and template featured-news.
It's possibly that this doesn't work anymore... but news_grid menu works, I am using it too. Doesn't there newest version on Fizi site?
I could check this, but I do support of themes on my forum. Fizi themes are the best and very well written, so I should be able to fix them.
