Can't see any threads open for similar issue - apologies if I've missed one.I've followed the instructions from another thread for setting up LDAP authentication.Downloaded, installed and enabled the plugin. Filled in all the details as directed, but then when I click Save the page doesn't save or go anywhere. I get a blank web page, which does nothing when being refreshed. Have to use the back buttons, or go back to the admin console. Settings do not get saved.Any ideas at all?
