Thanks for the tip, not sure why this is.
I tried your suggestion, composer worked, but then got
Using version ^7.0 for prestashop/autoupgrade
[abcmachine@becane www]$ php bin/console update:check admin123
Fatal error: Uncaught Error: Class "AppKernel" not found in /home/abcmachine/domaine.fr/www/config/autoload.php:28
Stack trace:
#0 /home/abcmachine/domaine.fr/www/config/config.inc.php(36): require_once()
#1 /home/abcmachine/domaine.fr/www/bin/console(15): require_once('/home/abcmachine...')
#2 {main}
thrown in /home/abcmachine/domaine.fr/www/config/autoload.php on line 28
Missing something...
Checks:
/home/abcmachine/domaine.fr/www/config/autoload.php does exist of course
Lines 27 and 28 are
require_once __DIR__.'/../vendor/autoload.php'; define('_PS_VERSION_', AppKernel::VERSION);
There indeed is an autoload.php in /domaine.fr/www/vendor
I can only find this type of error in much older posts and PSP 1.7 or so, and no relevant solution...
Thanks.
