as described by allanhartless I created the upgrade php file, copied it in my Mautic root directory and executed “php upgrade.php”
I get back messages, that you can see below.
Is putty the wrong tool? Or what other mistake do I make? Or is there a fix or something else?
For a tip I would be grateful
