installation error – superuser never has logged in

[ngrmm]

after the last step of the installation i got this:

Error: Call to a member function execute() on null (line 55 of /is/htdocs/wp12525122_ZO20H1QFL5/www/xxx.de/_tmp/index.php) 

This error message was shown because: Superuser has never logged in. Error has been logged.

i found this thread but the php-version isn't the problem. it's php 5.6

that the error log:

[Fri Jan 13 20:46:37 2017] [-:error] [pid 20774] [client xx.xx.xx.xx] [host xxx.de] PHP Fatal error:  Call to a member function execute() on null in /is/htdocs/wp12525122_ZO20H1QFL5/www/xxx.de/_tmp/index.php on line 55

any idea?

[ngrmm]

at first i got this error and after deleting install.php the above one

 

Error: Class 'InputfieldSelectMultiple' not found (line 7 of /is/htdocs/wp12525122_ZO20H1QFL5/www/xxx.de/tmp/wire/modules/Inputfield/InputfieldAsmSelect/InputfieldAsmSelect.module) 
This error message was shown because: install.php still exists. Error has been logged.

That's weird but it looks like you're working out of two different directories for the install. You have a _tmp and a tmp. Maybe double check the install directory and make sure that the htaccess file, and wire & site directories exist alongside index.php. Which version of PW are you using?
