Something has gone wrong with my custom theme. It appears to have broken all by itself. I’ll have it fixed as quickly as possible.
Update: The TTLB Ecosystem is at it again – the darn thing slows down and breaks my site quite often. I’m working on trying to figure out why.
Update 2: I’ve solved the issue by temporarily turning off the TTLB Ecosystem Cache plugin. The plugin sets the TTLB status to only update every 24 hours, which speeds up loading the blog but for some reason broke my theme. Will post another update once I figure out why.
