We’ve just updated our development server from 2.2.2 to 2.4. One of the first things I noticed is that the Multiple Site Manager will show a list, but when a site is selected it reloads the default site (so we cannot get to any of the other sites). I’ve checked to ensure that the files are present and it’s enabled. One item of note is that we are licensed for 78 sites and have 16 enabled on development, counting the default site. Not sure if that will make a difference. Any help with this would be appreciated - thanks!
