I am really hoping that someone can shed some light on this strange behaviour.
We have a client that is running all of their sites hosted on SiteGround, they are all Wordpress sites. We have gone ahead and installed wp-mautic plugin and when testing to see that anonymous users are converted to known users and being tracked it is just not working.
Now we have over 50+ other clients with Wordpress sites and everything is working like a dream… converting, tracking.
On these sites if I try in chrome or safari, it is not picking up the user, however if I do it in Firefox it converts the anonymous user to the known user and takes all the tracking history as well.
Anyone can shed some light, or point me how to debug. Maybe a plugin issue ?
