Thanks @rod_barbee, @Ben and @Matthew for your input.
Unfortunately nothing helped.
I have, however, found a solution.
When I originally created the host using MAMP Pro I asked for MAMP to generate a certificate for https access. I thought this was the best approach because, obviously, my actual online website is secure. The URL of this ended up as
But experiencing this problem made me a bit desperate as buying Backlight is a not insignificant investment so I deleted the host from MAMP Pro and created a new one but this time without asking it to generate the certificate for https access. After installing Backlight 3 this time the URL to the site is
http://bl.photography.pixelsnaps:8888 and now I get the default Contact and About pages with no problem.
That’s great but now I’ve noticed another issue: when I go to Designer > Templates and click Download Template Presets I get to the Backlight presets page but I then am unable to import any of the presets. For example, the error I get from Safari says: Not Found The requested URL /backlight/designer/list_templates/ was not found on this server. The URL being accessed is
My question, I suppose, is has anyone ever installed and run Backlight 3 on a Mac using MAMP Pro and if so, what do I need to do to get it to work?
