I need to add a new button next search button (upper right side) that will display “EN” and send visitors to the English version of the blog. I already tried Buttons Shortcode and Widget without any luck. Using this plugin I can only add a button in a page/post/widget.
Sorry this theme doesn’t support you add new button next on search button.
I think if you want to link your reader to English version, you can create a new menu with 2 dropdown menu item. Example: one item is French and one item is English.
