@KawaSeadrake There were a few patches that changed how some of the configuration files were permitted to be written, and a couple of those config files never got updated. They were config files that dealt specifically with localization, so I never encountered the bug during my site testing since it was usually in the US.
Also, our search page was really badly written so I re-wrote that today.
Lots of files missing error checking and handling stacked up over time. :x
@KawaSeadrake I've felt guilty about admitting what site I'm a dev for for a while because I've not had the time to handle cleanup of things like that. Our sites run horribly because of all the technical debt and I've just never had the time needed to clean them out.
