Upgraded a brand new 2.0.13 board to 2.0.17 using the "changed zip" files. The board is Subsilver with no mods. The "update to latest version" file was launched with no errors being reported. The install and contrib directories were appropriately deleted. Below is the error message I get when I attempt to log into this board:
phpBB : Critical Error
