I just upgraded a system I'm administering from 2.10 to 3.3.1. Everyhthing seemed to go OK, except that I have noticed a couple of problems.
1) When I try to send a Test mailing, after adding content in the 'Create Campaign' area, it flashes briefly, but no email is sent out. There are no errors reported on the page. But when I go to 'Log of Events', I see this error for each time I hit the 'Send Test Email' button:
Error sending email to <validEmail> Could not instantiate mail function.
The email address provided is one on the same domain as the PHPList is running; it is an email that is a subscriber. I don't recall exactly how I had this configured in the original 2.10 installation ( set this up about 5 years ago). I believe that I may have been using SMTP instead of PHPMailer(). But that's when I started to look at the Settings and ran into my second problem...
2) When viewing the Configuration -> Settings page, there is content in most of the fields and an 'Edit' button on each line, but there are no labels associated with each line. I have no idea what data I'm filling out.
For #1, shouldn't my settings that I hand coded into various configuration files in the old installation have been retained? Or did the new installation come in with completely new/default configuration files? Are there still many places that require manual editing of text files?
