ProxyPass worker name too long

Hi,

today I installed Nginx and PHP7 on a VPS with Plesk 12.5 running on Ubuntu 14.04 Server. Now I see the following error after login:

AH00526: Syntax error on line 52 of /etc/apache2/plesk.conf.d/vhosts/myhost.de.conf: ProxyPass worker name (unix:///var/www/vhosts/system/myhost.de/php-fpm.sock|fcgi://127.0.0.1:9000/var/www/vhosts/myhost.de/httpdocs) too long .

Does anybody have an idea of how to fix that?

Thanks!

Daniel
