So I'm quite sure in vanilla Minecraft, Lightning strikes will cause a fire. However, I'm sure one of my plugins may be blocking this vanilla function. If anyone would be able to figure out which one, I would be glad. Plugins (38): CoreProtect, LuckPerms, TimTheEnchanter, Masssay, ClearChat, Lift, ClearLag, CrackShot, Server_Monitor, NoSunlight, SocialLinks, Chairs, BuildersWand, EasyCarts, IntEx, Multiverse-Core, ProtocolLib, LibsDisguises, SkinsRestorer, FastAsyncWorldEdit, MaxBans, TimeChanger, DisableExplosions, Vault, WorldEdit, Essentials, Banknotes, HolographicDisplays, Citizens, DiscordSRV, SafestHouse, WERegionTeleport, EssentialsChat, TAB, SuperVanish, DispenserTools, EssentialsSpawn, AdminMode (Those that have seen my threads in Spigot Plugin Development should recognise some of these plugins, I'm sure they have no effect on this vanilla function.) (Those highlighted in Orange are those that are made by me)

If you use world guard, there is a world guard config setting in the config.yml that controls weather that you may have disabled
Always easiest way is to remove plugins by a few, 3-5 at once and test that way. Make sure to delete them and restart the server rather than removing with plugman. Once you see the issue fixed, add one by one the few removed plugins and you will find the one.
My custom ones aren't very complex, neither do any of them modify block or lightning capabilities. So I doubt it would be any of them
