I have a lovely new instance of openproject running on my server with apache2. I have changed the port to 8080 both in the /etc/apache2/ports.conf file with a new line

Listen 8080

and in the /etc/apache2/sites-available/openproject.conf file with the starting line

<VirtualHost *:8080>

I can now access openproject on port 8080 like http://example.net:8080. All good. But I can’t any more access my server root, which runs wordpress.org: http://example.net; I get the 403 error with

You don't have permission to access / on this server.

I’m not sure what openproject has done to the rest of my configuration: but I would like access to my blog again.

Any advice would be most welcome!

Well, I’ve spent most of the day wrestling with this: and I’ve hunted through all my apache2 configuration files, restarted the server multiple times, but I can’t access the /var/www/html/ directory (where wordpress.org is installed). So it seems that my installation of openproject has (I hope, only temporarily) broken my wordpress installation.

I’m still hoping for advice here…

Change the port of OpenProject to another port everywhere.

/etc/openproject/conf.d

/etc/apache2/sites-enabled/openproject.conf

Restart Apache server by

sudo service apache2 restart

For me it worked, but i am also trying to find a way to change OpenProject port.
