PHP error on Clan page

I have an error on the Clan page. I’ve not modified the functions.php file in any way. I get this:

“Warning: Illegal string offset ‘pending’ in /hermes/bosnaweb23a/b2209/ipg.shopwithloraliecom/Blackfyre/wp-content/themes/blackfyre/functions.php on line 2047 Warning: Illegal string offset ‘pending’ in /hermes/bosnaweb23a/b2209/ipg.shopwithloraliecom/Blackfyre/wp-content/themes/blackfyre/functions.php on line 2048”

These are the lines associated with it:

if(!isset($post_meta_arr[‘users’][‘pending’])) $post_meta_arr[‘users’][‘pending’] = array();
if ( is_array( $post_meta_arr[‘users’][‘pending’] ) ) {
