Fehlermeldung im Template

Hallo Zusammen,

Ich habe mir über Themeforest das Theme Overlay gekauft und heruntergeladen. Doch erscheint bei mir auf der Seite, auf welchem ich das Theme nun installiert habe immer die Meldung

[B]Warning: array_keys() expects parameter 1 to be array, string given in [B]/home/raphael1/public_html/wp-content/themes/Overlay/functions.php on line [B]180[/B][/B][/B]

An was kann dies liegen? Muss ich noch eine Zusätzliche Einstellung vornehmen, bevor ich meine Webseite bearbeiten kann? Besten Dank und freundliche Grüsse, Raphi
