Fatal Error

I’m receiving fatal error: Uncaught Error: Call to undefined method Composer\Autoload\ClassLoader::setClassMapAuthoritative() — line 38 of /wp-mail-smtp/vendor/composer/autoload_real.php.

I installed the plugin, followed briefings for articulating with gmail, provided an appropriate “to” address, and went for API. I had to extract “cient_secret” from downloadable client_id.json using text editor. I don’t think I’d done anything else before getting the fatal error.

I had been running php 7.2 on localhost MAMP on Mac, backed down to php 5.6 and got similar though less detailed error. Any suggestion would be deeply appreciated.

sciman@cpp.edu (note error in stored email address. I’ll try to update that immediately).
