Fatal Error

Hi, I encounter this problem when a user tries to recover the password:

Uncaught Error: Call to undefined function get_home_path() in wp-content/plugins/polylang-dynamic-sitemap-generator/polylang-dynamic-sitemap-generator.php:125 Stack trace: #0 wp-includes/class-wp-hook.php(310): dynamic_sitemap_generator_create_sitemap() #1 wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #2 wp-includes/plugin.php(517): WP_Hook->do_action() #3 wp-includes/post.php(4715): do_action() #4 wp-content/plugins/flamingo/includes/class-contact.php(202): wp_insert_post() #5 wp-content/plugins/flamingo/includes/class-contact.php(135): Flamingo_Contact->save() #6 wp-content/plugins/flamingo/includes/user.php(29): Flamingo_Contact::add() #7 wp-includes/class-wp-hook.php(310): flamingo_user_profile_update() #8 wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #9 wp-includes/plugin.php(517): WP_Hook->do_action() #10 wp-includes/user.php(2461): do_action() #11 wp-includes/user.php(2582): wp_insert_user() #12 wp-includes/user.php(2931): wp_update_user() #13 wp-content/plugins/user-registration/includes/shortcodes/class-ur-shortcode-my-account.php(416): get_password_reset_key() #14 wp-content/plugins/user-registration/includes/class-ur-form-handler.php(376): UR_Shortcode_My_Account::retrieve_password() #15 wp-includes/class-wp-hook.php(308): UR_Form_Handler::process_lost_password() #16 wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #17 wp-includes/plugin.php(517): WP_Hook->do_action() #18 wp-settings.php(645): do_action() #19 wp-config.php(100): require_once(‘…’) #20 wp-load.php(50): require_once(‘…’) #21 wp-blog-header.php(13): require_once(‘…’) #22 index.php(17): require(‘…’) #23 {main} thrown

Can anyone tell me how to solve it?

Thank you
