Broken website after update

Hi there,

thats a problem with a function in your Child Themes functions.php - do you have a function like this here for setting your color pallet ?

If so can you remove that, as the new Global Colors doesn't require it.

It was a custom theme developed so i have stuff like that :

function eb_add_css_in_head() {
	echo '<style>
	body.single .inside-article h2 {
	  border-left: 4px solid '.generate_get_color_setting('form_button_background_color').';
	  padding-left: 20px;
	}
	h1.entry-title:before,
	h1.entry-title:after,
	h1.page-title:before,
	h1.page-title:after,
	.special-title:before,
	.special-title:after {
	  color: '.generate_get_color_setting('form_button_background_color').';
	}
	.review-result-wrapper .review-result {
	  color: '.generate_get_color_setting('form_button_background_color').' !important;
	}
	.circular-chart .circle {
	  stroke: '.generate_get_color_setting('form_button_background_color').';
	}
	.button.cta {
			background-color: '.generate_get_color_setting('cta_button_background_color').' !important;
			color: '. generate_get_color_setting('cta_button_text_color').' !important;
	}
	.button.cta:hover {
			background-color: '. generate_get_color_setting('cta_button_background_color_hover').' !important;
			color: '. generate_get_color_setting('cta_button_text_color_hover').' !important;
	}
	</style>';
}

add_action('wp_head', 'eb_add_css_in_head', 99);

or

function gp_customize_cta_color( $wp_customize ) {

	$wp_customize->add_control(
		new GeneratePress_Title_Customize_Control(

			'generate_cta_button_colors',

				'settings' => ( isset( $wp_customize->selective_refresh ) ) ? array() : 'blogname',
				'priority' => 10,
			)
		)
	);

	$wp_customize->add_setting(
		'generate_settings[cta_button_background_color]',
		array(
			'default'     => $defaults['form_button_background_color'],
			'type'        => 'option',

		)
	);

	$wp_customize->add_control(
		new GeneratePress_Alpha_Color_Customize_Control(
			$wp_customize,
			'generate_settings[cta_button_background_color]',

				'section'   => 'buttons_color_section',
				'settings'  => 'generate_settings[cta_button_background_color]',
				'palette'   => $palettes,
			)
		)
	);

	$wp_customize->add_setting(
		'generate_settings[cta_button_text_color]',
		array(
			'default' => $defaults['form_button_text_color'],
			'type' => 'option',
			'sanitize_callback' => 'generate_premium_sanitize_hex_color',
			'transport' => 'postMessage',
		)
	);

	$wp_customize->add_control(
		new WP_Customize_Color_Control(
			$wp_customize,
			'generate_settings[cta_button_text_color]',
			array(
				'label' => __( 'Text', 'gp-premium' ),
				'section' => 'buttons_color_section',
				'settings' => 'generate_settings[cta_button_text_color]',
			)
		)
	);

	$wp_customize->add_setting(
		'generate_settings[cta_button_background_color_hover]',
		array(
			'default'     => $defaults['form_button_background_color_hover'],
			'type'        => 'option',
			'transport'   => 'postMessage',
			'sanitize_callback' => 'generate_premium_sanitize_rgba',
		)
	);

	$wp_customize->add_control(
		new GeneratePress_Alpha_Color_Customize_Control(
			$wp_customize,
			'generate_settings[cta_button_background_color_hover]',
			array(
				'label'     => __( 'Background Hover', 'gp-premium' ),
				'section'   => 'buttons_color_section',
				'settings'  => 'generate_settings[cta_button_background_color_hover]',
				'palette'   => $palettes,
			)
		)
	);

	$wp_customize->add_setting(
		'generate_settings[cta_button_text_color_hover]',
		array(
			'default' => $defaults['form_button_text_color_hover'],
			'type' => 'option',
			'sanitize_callback' => 'generate_premium_sanitize_hex_color',
			'transport' => 'postMessage',
		)
	);

	$wp_customize->add_control(
		new WP_Customize_Color_Control(
			$wp_customize,
			'generate_settings[cta_button_text_color_hover]',
			array(
				'label' => __( 'Text Hover', 'gp-premium' ),
				'section' => 'buttons_color_section',
				'settings' => 'generate_settings[cta_button_text_color_hover]',
			)
		)
	);

}

add_action('customize_register', 'gp_customize_cta_color');

Do i need to rewrite everything ?

Yeah - that color functions aren't going to work.
The possible good news is though you shouldn't require those PHP to do this now.
In the the new Global Colors see here:

https://docs.generatepress.com/article/using-global-colors/

you can add your own color variables. eg. my-color can be simply added to your CSS properties eg.

.element {
    color: var(--my-color);
}

So you just need a bunch of global colors to add into your CSS.

Thanks David for your help. I will try to do it myself so.

You're welcome
