Sometimes (with other products) I’ve encountered problems related to the browser used, so I tried this multiple times with Safari, Firefox, and Chrome. Same problem every time. Our site is hosted by GoDaddy, we are running WP 5.5 and PowerPress 8.3.5, and I’m not sure where the problem is.

Any help you can provide is appreciated!

The grid of media center doesn’t show any files. It ends in an endless loop showing no thumbnails.

tinyMCE shows text only if you choose it. The menu is not visible.

It happens in Edge as well in Firefox. This behaviour is new. It appeared after 09/24.

What may be the reason for these misfunctions?

Customizer codes here :

function wv_customize_register( $wp_customize ) {
$wp_customize->add_section( 'wv_background_settings' , array(
    'title'      => __( 'Background Settings', 'wv' ),
    'priority'   => 30,
) );
$wp_customize->add_setting( 'wv_background_color' , array(
    'default'   => '#000000',
    'transport' => 'refresh',
) );
$wp_customize->add_control( new WP_Customize_Color_Control($wp_customize, 'bck_clr', array(
	'label'      => __( 'Background Color', 'wv' ),
	'section'    => 'wv_background_settings',
	'settings'   => 'wv_background_color',
) ) );

 

}
add_action( 'customize_register', 'wv_customize_register' );

?>

<style type='text/css'>
body{background-color:<?php echo get_theme_mod('wv_background_color') ;?>;}
</style>

 
<?php
 
function wv_customize_css()
{
    ?>
         <style type="text/css">
body{background-color:<?php echo get_theme_mod('wv_background_color') ;?>;}
         </style>
    <?php
}
add_action( 'wp_head', 'wv_customize_css');

?>

But when remove this codes , uploading works.
