Illegal String Offset

Question

My arrays are defined as `<?php if ( $active_tabs['latest'] ) { ?><li class="active"><a href="#latest-posts-<?php echo $id; ?>" data-toggle="tab"><?php _e('Latest', 'radium'); ?></a></li><?php } ?>
<?php if ( $active_tabs['popular'] ) { ?><li><a href="#popular-posts-<?php echo $id; ?>" data-toggle="tab"><?php _e('Popular', 'radium'); ?></a></li><?php } ?>
<?php if ( $active_tabs['featured'] ) { ?><li><a href="#featured-posts-<?php echo $id; ?>" data-toggle="tab"><?php _e('Featured', 'radium'); ?></a></li><?php } ?>

but returns an Illegal String Offset on this line <?php if ( $active_tabs['latest'] ) { ?>`

Could anyone explain why?
