I have a confusing problem. I have an email form finisher and neos/swiftmailer installed and configured in the settings. It doesn’t work. I have been trying for hours to find the problem.
Debbuging doens’t work, it’s seems like Swiftmailer never gets activated. The code is similar to another project.
It seems like the configuration is being reset, that could be due to a wrong loading order mentioned by Karsten. How do you require the swiftmailer package and in what order is it listed compared to your own package?
