Munchkin cookie disappears if user refreshes the page after giving consent to cookies

Hello again!

 

We have created a landing page, where the munchkin cookie disappears when you refresh the page (after accepting all cookies):

<deleted-url-to-site>

 

Does anybody have an idea of what can be causing this issue?

 

The setup:

- Cookie-banner is set via GTM container.

- If user gives consent a trigger fires, that sets the Marketo Munchkin cookie.

 

Any help would be much appreciated!

 

Best,

ernie

Your cookie consent code is explicitly deleting it on refresh. As you can see here, the variable o is empty, which is how you delete a cookie.

Re: Munchkin cookie disappears if user refreshes the page after giving consent to cookies

Hi @SanfordWhiteman!

 

Thanks for your prompt response!

 

Now, do you have any idea as to why this is happening?

 

When I check the console, there is also a warning, when you refresh the page, saying 'Cookie “_mkto_trk” has been rejected for invalid domain.'

 

I think that this is the reason as to why the cookie is being set with an empty string  - its being deleted because the domain is invalid for some reason. But I simply cannot figure out why. 

 

Thanks in advance!

Your cookie consent code does have a “tree-walking” test where it tries to delete and reset the cookie at every possible parent level (not a very well-written test, I must say). You’d have to talk to the vendor to discover how you can ensure the cookie is preserved, rather than being deleted and never recreated.
