Debugging in WordPress at Theme installation

Try installing the Theme manually.

If still no joy, I suggest asking in the theme’s support at https://www.ads-software.com/support/theme/house-state so the theme’s developers and support community can help you with this.

Thanks @t-p . Actually I tried with other Themes. But I got same result. I can install Theme Manually. But I would like to solve the issue. Thanks @t-p .

I can install Theme Manually.

Glad to know you can install manually ??

But I would like to solve the issue

Auto update can fail for a large number of reasons and it is often hard to diagnose the failure due to specific configurations present on each server running the update.

There are many more reasons that things could have failed. Honestly there’s no good way to track down why a partial update occurred, we can only recommend what to do if one does occur — Manually installing/updating.

Thanks @t-p . I found the issue is in this function of wp-admin/includes/class-file-upload-upgrader.php. Here is the function

public function __construct( $form, $urlholder ) {

		if ( empty( $_FILES[ $form ]['name'] ) && empty( $_GET[ $urlholder ] ) ) {
			wp_die( __( 'Please select a file' ) );
		} 
}
