Testcookie causes warning in browser console #17829

reported in https://forum.matomo.org/t/javascript-error-trying-to-set-test-cookie-pk-testcookie-domain/42655

Since Matomo 4.4.0, setting the testcookie seems to cause this error to be logged in the browser console:

There was an error setting cookie _pk_testcookie_domain. Please check domain and path.

I just updated to 4.4.0 and get a similar Error:

In our container cookies are disabled, but when i use a private/icognito browser window i get
There was an error setting cookie_pk_id.X.XXXX. Please check domain and path.

Same here. I see the same error like @meibegger

This error message shows up on all Matomo installations running v4.4

@mtoensing, @howdytom This has been fixed with #17830, which will be released in 4.4.1. If you want to test the fix, you can already install the release candidate for it.

Hi there,

I updated to release 4.4.1 when it was first available. But this issue is still there. So what would you recommend to do?
Could you reopen this?

@mamorg79 Is it exact that warning? Are you maybe using the tag manager? If so maybe you need to release a new container version. Otherwise did you clear the browser cache to ensure it's not a caching issue?

Sorry for the inconvenience, some of my developers published an old script and there was an mistake placed in it.

I have a similar error. How can I solve it

We have multiple sites that show this exact same issue on inconito and private browsers. Running the latest 4.13.0 self hosted version. How can we get this fixed?
