A combination of being too tired, hungover, and burnt out, and accidents will happen. Working on code is always a bad idea in that particular scenario.
I accidentally erased the Infovore template and stylesheet. Thankfully, I saved the template, but only had a six-month old copy of the stylesheet. So I had to do my best to rebuild it. We’re just about there, but the menu isn’t finished.
Ah well. Infuriating hour and a bit rebuilding it, I tell you. I’ve learned my lesson for next time…
