PHP errors wc_coupons_enabled

Hello,

We’ve trying to resolve some PHP errors, specifically:

PHP message: The WC_Legacy_Cart::coupons_enabled function is deprecated since version 2.5.0

[Thu Feb 04 20:30:45.884429 2021] [proxy_fcgi:error] [pid 2056:tid 139929531037440] [client IP.ADDRESS:60144] AH01071: Got error 'PHP message: The WC_Legacy_Cart::coupons_enabled function is deprecated since version 2.5.0. Replace with wc_coupons_enabled.PHP message: The WC_Legacy_Cart::coupons_enabled function is deprecated since version 2.5.0. Replace with wc_coupons_enabled.', referer:

This appears to be caused by the following code:
/custom-checkout-layouts-for-woocommerce/WooCommerce/cart/cart.php

?php if ( wc_coupons_enabled() ) { ?>
						<div class="coupon">
							<label for="coupon_code"><?php esc_html_e( 'Coupon:', 'cclw' ); ?></label> <input type="text" name="coupon_code" class="input-text" id="coupon_code" value="" placeholder="<?php esc_attr_e( 'Coupon code', 'cclw' ); ?>" /> <button type="submit" class="button" name="apply_coupon" value="<?php esc_attr_e( 'Apply coupon', 'cclw' ); ?>"><?php esc_attr_e( 'Apply coupon', 'cclw' ); ?></button>
							<?php do_action( 'woocommerce_cart_coupon' ); ?>
						</div>
					<?php } ?>

Is there a way to confirm and resolve this ?

Many Thanks
