A potential security issue was found in the theme. It was not imported. Please contact the Author or MyBB Group for support.

i'm on 1.6.10

open theme's xml file in a text editor (eg. notepad++), do following edits, save the file and use it

change {$monthnames[$prev_month['month']]} to {$prev_month['month']}
and replace {$monthnames[$next_month['month']]} with {$next_month['month']}
