Why am I seeing this privacy consent pop-up when I visit PistonHeads?

We are legally required to ask for your consent to cookies every 30 days. We use a third party tool called Quantcast as our Consent Management Platform (CMP) to keep us in line with GDPR rules and European cookie law. It's a fairly standard bit of kit you'll find on a lot of websites hosted in Europe like Buzzfeed, Reach Media, Immediate Media, and a lot of other publishers.

I'm seeing it more than every 30 days. Why?

There are a number or reasons why you may be seeing this more often than you should. This may be:

• That you're using an ad blocker or other browser extensions that are interfering with a cookie being stored
• You're using an unsupported browser, such as Brave
• You're clicking through to our website from social media or an in-app browser, which is treated as a new session every time
• You're using a private browsing or incognito mode

How can I stop it?

• Use a major supported browser such as Chrome, Firefox or Safari
• Switch off ad blockers and/or try toggling other extensions on/off that may be interfering
• Use standard browsing modes, not private/incognito
• Try clearing your cookies for PistonHeads

That hasn't helped – what else can I try?

• Safari – Go to Preferences under Safari menu/privacy/'manage website data'. All the sites will load. Search 'piston'. PistonHeads pops up. Remove all
• iPad – go to Safari in settings and try removing all website data
• Chrome – Try clearing Local Storage through the developer toolbar. View > Developer > Developer Tools > Application > Storage > Local Storage > right click https://www.pistonheads.com > Clear
• Another Local Storage potential fix – the source of the issue may be down to a value in the browser's local storage called "_cmpRepromptHash". If you're an advanced enough user to find that value, delete it and the problem will go away (after agreeing / disagreeing once more).
• Try a full browser reset
• PiHole users – Using the inspector I'm seeing that the following URL failed to load as it couldn't find the hostname: https://audit-tcfv2.quantcast.mgr.consensu.org/?lo... Changing to a google DNS on my machine made it load. This is the regex for the whitelist that's working for me now:

  https://audit-tcfv2\.quantcast\.mgr\.consensu\.org.*$
