I have a Ubuntu Server (16.04.3 LTS) with Apache 2.4.18 and redmine installed, following this installation guide.
Therefor I edited the ssl.conf in my
apache2/sites-available and added those lines:
<IfModule mod_ssl.c> <VirtualHost _default_:443> ... <Directory /var/www/html/redmine> RailsBaseURI /redmine PassengerResolveSymlinksInDocumentRoot on </Directory> </VirtualHost> </IfModule>
This used to be working for several months, but today I edited the
ssl.conf to add another location. Now the Apache restart fails and
systemctl status apache2.service shows the following error message:
Invalid command 'PassengerResolveSymlinksInDocumentRoot', perhaps misspelled or defined by a module not included in the server configuration
Neither did I change anything in the redmine part of
ssl.conf nor did I enable or disable any Apache modules.
Even reverting the changes doesn't help avoiding this error message.
PassengerResolveSymlinksInDocumentRoot makes Apache work again, but disables the redmine installation.
passenger-config validate-install returns zero errors if the line is commented, and 'Your Apache installation might be broken' if the line is uncommented.
Is there any way to fix this or are there any other files I should check to fix this error?
