Thread:Project:Support desk/Infoboxes are gone and script error is displayed at the top of every page

I'm really ignorant to how all this works I just try my best to follow instructions. Yeah so ever since I special imported template:infobox church my infoboxes disappeared. On top of that I see "Script error" on every page above the text. On one page I see "Lua error in Module:Infobox at line 229: attempt to index field 'html' (a nil value). Backtrace: (tail call): ? Module:Infobox:229: ? (tail call): ? mw.lua:553: ? (tail call): ? [C]: in function "xpcall" MWServer.lua:73: in function "handleCall" MWServer.lua:266: in function "dispatch" MWServer.lua:33: in function "execute" mw_main.lua:7: in main chunk [C]: ?"

It's slightly different on other pages. How can I fix this and get my infoboxes to show?
