So... that was fun.
Round 1:
Attempted to upgrade to SMF 2.x. It didn't go well.
Internet at home started cutting out and then died. Which has never happened previously except for severe storms.
Went into work.
Undid the SMF 2.x install, reinstalled 1.1.21. Re-enabled certain add-on packages (anti-spam).
Round 2:
Icons fixed.
Didn't remember the exact order of the boards. So... I just put the boards in an order that kinda sorta made sense, kinda sorta random. Good enough for government work.
Set file permissions to more secure settings. Previously some were 777, which was very bad.
Think that's everything. Going home, today sucked.
Lemme know if anything else is hinky.
