Can't update from 4.2 to 4.2.1

na alleen het aanpassen van regel 149 lukt het nog niet.
nu de volgende fout; PHP Fatal error: Call to undefined function wp_print_request_filesystem_credentials_modal() in D:\LocalUser\XXXXXXXXXXXXXXX\html\wp-admin\plugins.php on line 487

nevermind reinstalled the initial files without my child theme.
Now the plugins are reacheble.

Will disable them and then change the file.php file and then do the update.
I will post the result afterwards

Guys and girls,

all went well until i was copying the new files (4.2.2) back) got a weired msgs from fillezila, even this didn’t help: https://forum.filezilla-project.org/viewtopic.php?t=34963

So i am now copying back the 4.2.1 version (also uploading with filezille) no problem.

Will dive in to this tomorrow. need sleep (4 in the night now)

Have a good one all, cya
