Fatal error

Dear Support

I just updated the pluggings that the dashboard asked me to do it, and now I got an error

Fatal error: Can’t use method return value in write context in /home/ljimeno/public_html/summerdreamhotels.com/wp-content/plugins/woocommerce-gateway-paypal-express-checkout/includes/abstracts/abstract-wc-gateway-ppec.php on line 231

On the file abstract-wc-gateway-ppec.php the line 231 is: if ( ! empty( $creds->get_username() ) ) {

…
/**
* Validate the provided credentials.
*/
protected function validate_active_credentials() {
$settings = wc_gateway_ppec()->settings->load_settings( true );
$creds = $settings->get_active_api_credentials();

if ( ! empty( $creds->get_username() ) ) {

if ( empty( $creds->get_password() ) ) {
WC_Admin_Settings::add_error( sprintf( __( ‘Error: You must enter a %s API password.’ ), __( $settings->get_environment(), ‘woocommerce-gateway-paypal-express-checkout’ ) ) );
return false;
}
…

Could you please advice?

Thanks in advance and warm regards
