I am trying to setup a local LAN test server running OSX El Capitan running Server5.1.7 with the WPMUdev-MultiSite plugin:
I managed to changed the wp_config.php to include the line "define_wp_multisite" and reloaded the WP dashboard.
I changed the MAMP apache port to 80.
Try to restart MAMP server but apache is not starting.
I check the local running process and found a list of httpd process on port 80 and follow a series of terminal command "launchctl -w unload" to remove the apache httpd.
Now I check the local running process and its clean of any port 80 process.
But when I try to start MAMP, the apache on port 80 will not start. Only the MySQL started.
Please help on how to enable port 80 running apache for MAMP as this is critical to the running of the Multisite, which is my main purpose of using your solution.
