Hi,
Unfortunately, no, I’ve not yet figured the problem out. I have installed and am using NextGen Gallery on several other sites none of which are exhibiting the same behavior.
I am not doing any 301 redirects on this site (the client’s previous site was removed from the internet by a rogue developer several months before this site was published.)
Any other thoughts are greatly appreciated though. (I have changed the landing page slideshow to load a single image rather than display that rotating loader image.)
Peace,
-Kenny
