Hi Wes,
Thanks so much for your quick responses and for taking the time to look at this for me.
In the end it turned out to be a conflict with another plugin (not W3C-TC as I had initially thought – mostly because that was the last plugin that had been added). Once I removed that the site/theme loads great and page-load speed (which is what this was all about) is at 1.9 sec on Pingdom and 2.7 on GTMetrix so I’m pretty happy with those stats on a photography site with lots of large images.
I greatly appreciate the quality of your themes and speed and commitment to support.
Cheers,
Debra
