Widgets fatal error

I all of the sudden started having issues with my widgets for my sidebar. I can’t drag and drop anything to show up in the side bar. Specifically the About me section.
I’m also getting a message that there are two inactive widgets, which include the Barletta social widget and the Barletta About me widget. But I can’t move them anywhere.

This is the message I receive at the bottom of the widgets page:
Fatal error: Uncaught Error: Call to a member function get_settings() on string in /home1/ionlycam/public_html/wp-content/themes/barletta/functions.php:286 Stack trace: #0 /home1/ionlycam/public_html/wp-includes/class-wp-hook.php(286): barletta_check_sidebar_params(Array) #1 /home1/ionlycam/public_html/wp-includes/plugin.php(203): WP_Hook->apply_filters(Array, Array) #2 /home1/ionlycam/public_html/wp-includes/widgets.php(710): apply_filters(‘dynamic_sidebar…’, Array) #3 /home1/ionlycam/public_html/wp-admin/includes/widgets.php(100): dynamic_sidebar(‘wp_inactive_wid…’) #4 /home1/ionlycam/public_html/wp-admin/widgets.php(421): wp_list_widget_controls(‘wp_inactive_wid…’, ‘Inactive Widget…’) #5 {main} thrown in /home1/ionlycam/public_html/wp-content/themes/barletta/functions.php on line 286
