applying modified file

I’d like to modify Iconbox.

Now iconbox has two option: with icon on top, with icon on left.

I’d like to have a third option: no-icon, that allows me to remove the icon (I know that iconbox without icon is a nonsense but I’ve seen that Iconbox is the best base for the result I wanna reach) and then I’ll add the possibility to choose a background color for the box and a font color.

I tried to modify iconbox.php file in themesenfoldconfig-templatebuilderavia-shortcodes : I added the third option and modified the outputted DIV as I want.

It works … Now I’m trying to add the other two options (font color and background) but I see no results… The impression is that the server is using a version of iconbox.php file cached somewehere…. I tried everything, deleting iconbox.php from the server, changing the theme and then reapplying Enfold, but nothing worked …. how can I force the server to reload the file modified? (and why the first modifications had been applied?)

Thank you all
