My Mautic version is:4.4.6
My PHP version is:8.0
My Database type and version is:10.5.18-MariaDB
My problem is:
The tracking pixel in emails does not load and does not record the opening of the email.
But if I load the url of the pixel in a separate tab, it registers the opening.
After opening the email, an email is scheduled to be sent, but it is never sent, unless the tracking pixel gif is opened in a new tab.
These errors are showing:
Web Bug from https://mydomain.com/email/63efd77371c25269430939.gif
Steps I have tried to fix the problem:
Change email tester, try in different scenarios (Browsers, receiving accounts, allow all traffic, try different installations for example an ec2 instance and from a cpanel) and always the same problem.
