@matthieuscarset, still struggling to upgrade the plugin.
This time it was activated (had to delete it and reinstall it through), but when I try to import campaigns it get the error captured by this image:

Only four out of ~150 campaigns were imported.
In addition, when I looked at settings later, the user name was replaced by “MailChimp”.

Thank you, @matthieuscarset.
There are still activation errors:

Plugin could not be activated because it triggered a fatal error.

The fix has already been applied.
In function travelify_scripts_styles_method, this change was made:

from:
wp_register_style( ‘google_font_ubuntu’, ‘http://fonts.googleapis.com/css?family=Ubuntu’ );

to:
wp_register_style( ‘google_font_ubuntu’, ‘//fonts.googleapis.com/css?family=Ubuntu’ );

The latter method is protocol agnostic and browsers don’t throw errors for https pages.

OpenSSL is not installed on my server.
I suspect the problem is due to that.
