I got it to work, I just needed extra menus.



original thread:
The server options won't work, when I try to change an option, for example I set the doom-style doors to yes but when I press return and go back to the cheats menu, it says no again and doesn't save. does the same when exiting the menu itself. and says "The addon "gmDoom" is creating errors" and the error is this.

"[gmDoom] lua/doom/convars.lua:29: attempt to call field 'CvarSet' (a nil value)
1. unknown - lua/doom/convars.lua:29
2. unknown - lua/includes/modules/concommand.lua:54"

Any questions? and no workarounds, I want a fix. I've seen other people's threads about this but no replies.

for those questions that you might comment.
1: I did use singleplayer.
2: I did host the server with 2 players and everything set to 99999 and still didn't work.
3: I used the Doom II official wad by getting the Doom collection on steam so no piracy.
4: I have both gmDoom maps and gmDoom itself.

extra thing: If you wanna bind the menu to a key do "bind <Key> doom_cl_menutoggle" no quotation marks.
