Thank you. I updated PHP but that did not seem to make a difference. I did work out the issue after coming at the problem with fresh eyes today. When I updated Connections, it had not applied a Template and with the template option blank, the directory would not load.
I still need to work out why the alpha index doesn’t work but I’m sure that as I play around with the updated system, I’ll work out the kinks.
Thank again, this has proven a very helpful plugin.
