Also, apparently something else is also behaving differently on NearlyFreeSpeech, breaking the ImageMagick processor. I compensated with an awful hack and, just to be sure, pregenerating all of the view images so I can go to bed without, hopefully, leaving photos.xythian.com woefully broken.
I think NearlyFreeSpeech is going to have to go. They seem fine for relatively static web sites, but trying to run applications there is like tearing my hair out. Testing on my home machine is completely irrelevant for determining if it’s going to work at all on NearlyFreeSpeech.
