Your problem
My problem is:

We upgraded an instance of Mautic to 4.1.0 and everything was working the way it should. It worked for about a week or so and then all of a sudden tracking stopped working today.

I am not seeing anything in the mautic.error log. On the Wordpress side I am seeing a 500 error in the console:

I have CORS enabled and in the mautic.access log I see the following:

Steps I have tried to fix the problem:
Tracking was enabled via WP plugin WP-Mautic. Also added the entire script to the header.
Added index.php to the end of my mautic url
chown -R www-data:www-data entire mautic directory
cleared cache between each change of action

@robm

Does anyone have any ideas here ? could this be a CORS issue ? Any idea how to go about troubleshooting this ?

We never did figure this out but upgrading to the latest version did the trick.
