Hey there, it seems the only mod that is causing problems is Resource Loader. UE ResourceLoader{1.3} [Resource Loader] (ResourceLoader-MC1.7.10-1.3.jar)
You can tell by the UE before the mod name. Which indicate how the mods have loaded. States: 'U' = Unloaded 'L' = Loaded 'C' = Constructed 'H' = Pre-initialized 'I' = Initialized 'J' = Post-initialized 'A' = Available 'D' = Disabled 'E' = Errored

PermissionsEx on Sponge servers and PermissionsEx on Spigot/Bukkit servers are completely different and use different commands to configure the plugin itself. Please follow the instructions on the following site to be able to give yourself OP permissions. (Do the commands via Console to start with)
Hey there Amber, The reason why your kit isn't working is because you've added an enchant to the iron hoe. To allow the kit to work change unsafe-enchantments from false to true.
