Hello! I see you're having trouble checking out on the M&S site, with a message about site issues. I'll do my best to help you through this.

Can I ask a couple of quick questions to get a clearer picture? Are you using the M&S app or their website on your Windows device? Also, is the problem happening consistently at the checkout step, and do you see any specific error messages besides "site has issues"?

While you reply, I can share some context: Recently, M&S has experienced ongoing technical challenges related to cyber incidents that have affected online ordering and payments. This has led to temporary pauses and errors in checkout for some users.

To start troubleshooting on your end, try these steps:
1. Clear your browser cache and cookies on your WebKit browser on Windows 10.
2. Close and reopen the browser, then try again.
3. If you're on the app, try uninstalling and reinstalling it.
4. Check if your internet connection is stable.
5. Try an alternate payment method if possible.

If you've done these already, please let me know. If the issue persists, it might be linked to the ongoing site-side problems M&S has been addressing. In that case, I can help you find alternative ways to place your order or provide updates on the site status.

Could you please share what steps you've tried and any specific error messages you see? That will help me guide you better.
