Plesk 12.x / Linux :: Wordpress Toolkit Parse Error - Cannot Connect To DB

I have over 5 WP installations on my Server and i installed all manual and had never issues.

Now i installed a again a WP Site and after i go to the Wordpress Toolkit to search for the new installation i got the following Message:

PHP Parse error: syntax error, unexpected '?' in /usr/share/plesk-wp-cli/php/wp-cli.php(23) : eval()'d code on line 1 {"err_code":0,"err_message":"

With error cannot connect to DB.

So all WP installations are running fine instead of the new one.... I didn't change any configs files of PHP all is standard, the wp-config.php is correct, the Site is running fine.

From my point of view is this an issue by Plesk due to Parse error message at the files of Plesk, see error message!

System:
OS Debian 7.8
Plesk Version 12.0.18 Update #43, zuletzt aktualisiert: 20. April 2015 13:17:36

I know with an older Version of Plesk 12.0.18 it was working fine too, so the bug was implemented with a MU.

I checked the file as well and find out that at all PHP files the code is not closed at the end so the "?>" is always missing.
