Undefined array key “ssba_bar_buttons”

Hi Khanhvo,

Thanks for reaching out, and I totally understand how frustrating constant error log entries can be.

This warning is due to the Simple Share Buttons Adder plugin referencing an array key (ssba_bar_buttons) that doesn’t exist when it’s expecting it to. This can happen with PHP 8.2+, which is stricter about undefined array keys. Here’s how to resolve it:

You or your developer can modify the plugin code around line 602 to prevent the warning. Replace:

$network_color = 'Y' === $arr_settings['ssba_new_buttons'] || 'Y' === $arr_settings['ssba_bar_buttons'] ? self::get_button_color( $button_name ) : '';

With:

$network_color = (isset($arr_settings['ssba_new_buttons']) && $arr_settings['ssba_new_buttons'] === 'Y') || 
                 (isset($arr_settings['ssba_bar_buttons']) && $arr_settings['ssba_bar_buttons'] === 'Y') 
                 ? self::get_button_color( $button_name ) : '';

This will check if the keys are set before accessing them, which avoids the PHP warning.

If you’re not comfortable editing plugin files, I recommend contacting a WordPress developer or the plugin author directly for a more permanent fix.

Let me know if you’d more help.
