- [x] a bug report
- [ ] a feature request
- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

Not change the cell background color

What is the current behavior?

Grey background cells are changing to black

What are the steps to reproduce?

Create spreadsheet with grey background cells Use IOFactory::load to load the spreadsheet Use the Xls writer to write a new spreadsheet

Please provide a Minimal, Complete, and Verifiable example of code that exhibits the issue without relying on an external Excel file or a web server:

<?php

require __DIR__ . '/vendor/autoload.php';

$spreadsheet = IOFactory::load('input.xls');

$writer = new Xls($spreadsheet);
	header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
	header('Content-Disposition: attachment; filename="output.xls"');
	$writer->save('php://output');

Which versions of PhpSpreadsheet and PHP are affected?

Works fine in 1.16.0. I noticed it broke in 1.18.0. Didn't test 1.17.0. I did look closer and 1.16.0 has a different shade of grey than what is originally there, but it's not doing what the latest version is doing which turns it to black.

I'm using Trisan's fork.. Has anyone run into an issue where some checkbox will check and some won't? Definitely using the correct names and everything. Just specific checkboxes won't check even though I can manually check them.

Hello, I'm trying to implement the plugin with private uploads. Should these be viewable in Wordpress admin itself? The files upload but I can't seem to view them in Admin -> Media.

I've set the following: add_filter( 's3_uploads_is_attachment_private', '__return_true' );

and define('S3_UPLOADS_OBJECT_ACL', 'private');
