After a couple of days of this entire site being down and then only the photo gallery, which embeds photos into each post, not working, I am happy to announce that I’m back up.
A PHP memory issue was causing the photo gallery to stop functioning. I hadn’t told WordPress to use more memory from PHP. My host allows me to use 256MB of memory, where WordPress was limited to a measly 32MB.
I’ll write a summary of all the things I had to do to get my site back up over the last few days. But if I may tease you a bit about it, it required editing DNS and PHP configurations.
