I can`t find extendedcrafting-common.toml in server/config, how can I fix this？

That file should be wherever your config files are. I think Iron Jetpacks also can cause this issue, which would require you to go into the config for that mod and disable all of the options in the dynamic recipe section. This would mean that all of the jetpacks won't have recipes and they would all need to be added manually.
