Countdown and text of..

When you created the menu item, have you selected "dealplazza" in the "select the template" option?

Yes i did it. i will try to fix it again from the beginning.

ok. i did it again and now it works. but could you tell me why it shows also offers from other categories? what is the configuration that i have to do to show only the items from this category? And something else, when i wrote a category name to the greek language, doesn't looks like the english (see ΑΡΧΙΚΗ ΣΕΛΙΔΑ-ΠΕΡΙΟΧΕΣ etc) and compare it with the ''categories''. How i can change the font to looks more pretty than this one?
Sorry for all that questions. I dont want to be tiresome or annoying.

To make only single category is displayed, please select only category you want to display in the "Select Categories" options (See img1)

And something else, when i wrote a category name to the greek language, doesn't looks like the english (see ΑΡΧΙΚΗ ΣΕΛΙΔΑ-ΠΕΡΙΟΧΕΣ etc) and compare it with the ''categories''. How i can change the font to looks more pretty than this one?

This is probably because the font that is used for the menu item (BebasNeue) doesn't have a fully support for greek languange. There are several ways to change the menu item font. I'll let you know the easiest one, so you can change the font without touching the CSS/PHP code.
From your joomla backend please go to : Extensions > Template Manager > Deal Plazza. From the Google Font Overriding tab in the left side, enable the 1st Font. Then fill all field as the img2.png attached below. Hope this helps

Thanks a lot i will try it in a while.
