What ever you are trying to use with ipairs isn't a table. The script would be helpful...

You only have constants in that script, so you are missing some lib file.
If you are using 0.2 just update your global.lua, I suppose they are in xxx-constants.lua? on 0.3, 0.4 series.

I cant take another constant.lua and change by the actual one, because i can mess with another function.. Can u be more exactly on wich function i am missing?

(i am having problem posting here constant.lua (+ than 10000 characters). If u guys need i will post in 3 parts...

Read the script, serach for isInArray(array, value).
The array is what you are missing, that should be enough to fix it yourself.

isInArray is receiving nil values, so I'd assume ensuring the tables exist would be helpful.

I cant even find InArray in my 000-constant.lua file (inside libs). It doesnt exist. LOL
How can i add this?

Edit: I look for "array' in other 3 otserver folder and do not found "array" on their constant,lua file...

isInArray is used in door.lua. isInArray is a function that uses a for loop and ipairs to find all the values within an array (table) and compare them. You need to ensure that the array being put into the function exists.
Example:
Code: 
if(isInArray(specialDoors, item.itemid) == TRUE) then

does specialDoors exist? Not that I can see. It may be intended to be used as a constant but regardless, it does not exist. @WibbenZ seems to be recommending that in 000-constant.lua, the constant tables like "specialDoors" need to exist. If they do not, you can copy them from a newer lib file and paste them into there if you absolutely cannot replace the existing one. Alternatively, you could make them local variables within door.lua. But they MUST exist to be accessed within door.lua.

Wait, i found this part:
keys = {2086, 2087, 2088, 2089, 2090, 2091, 2092, 10032, 10091}

on anotther lib from anotther otserver.. Let me test...

okay, try looking at a newer constant.lua and see if keys exists in there. otherwise, you can create the table yourself I suppose and add it to constant.lua.
Code: 
keys = {2086,  2087, 2088, 2089, 2090, 2091, 2092}

Edit: guess you found that part already xD

mainly the lib folder, those files often contain things that are required to make the server work, so if they're out of date, things may act up as is the case in this script :p
