This is a shop button for the 'Epsilon' theme by Bloc. This theme uses a text-based menu, so we don't need a shop button image
Code modifications:Open Themes/epsilon1.1rc2/index.template.phpFind:
echo '<li><a href="', $scripturl, '?action=calendar">', $txt['calendar24'], '</a></li>';
Add After:
echo '<li><a href="', $scripturl, '?action=shop">Shop</a></li>';
Your shop button should now be working!
