Having issues with certain websites and apps

That website uses a couple of redirects, but works fine here, on iPadOS 18.6. (No macOS 15.6 handy to check.)

Please download and run (free) EtreCheck, and share the results to the clipboard. Then open a new reply here, and press the Additional Text button that looks like a printed page, and paste and post the hardware and software configuration report here. From that, we can get a little more detail about what is installed and what is running here.

If these are apps you're using, which are not Apple Apps, contact the app developers for help with their Apps. Apple has no control over 3rd party applications. They don't own the code in them nor can they fix them. It's up to the app developers to ensure their apps are updated for the latest iOS updates.

You can check to see if there are app updates for the apps. You can delete the apps and reinstall them and see if that helps.

I've updated my Mac software, emptied cache, etc. Safari is still unusable. Pages won't load. The Ebird site works perfectly fine in Chrome on my Mac M1. My internet connection is perfectly fine. Safari is broken.

ravelry.com

instagram.com

hannaford.com

I can't log into any of these sites on Safari. When I click the login button, the page refreshes removing my login info rather than logging into the sites. The Hannaford site gives an Access Denied message " Access Denied

You don't have permission to access "http://www.hannaford.com/user/login.cmd" on this server.

Everything is working fine in Chrome.

They work fine on my MacBook Pro, iPad Pro, iPhone 16 Pro Max.

Do you by chance use a VPN or Anti-Virus tools on your devices? If yes, the are completely unnecessary and cause connectivity issues. They don't provide the security you think they do either.

I don't know what else to suggest. The sites you referenced work just fine on my devices.

You should contact Apple Support for direct help. If you're in the US, you can call Apple at: 800-MY-APPLE or tap the Support button at the bottom of this page.

FIXED!

I just unchecked "block all cookies" in my Safari Privacy settings and now everything works normally.

Weird because I hadn't made any changes to my settings anytime recently. My Safari problem started a few days ago while I was traveling. I was still having the problem after returning home. Not sure if "block all cookies" had always been checked in my settings or not. Unchecking it seems to have cured whatever was wrong.

Thanks for taking a look and trying to assist.

Can you share one of the websites you're having an issue with?

No VPN. No anti-virus.

I'm glad you got it sorted and it was a simple solution!
