(Big Dig 1.5.2) MCPC Server Essentials Not Working

[jjoeyay]

I have set up a Big Dig server, which runs on Minecraft 1.5.2, using the Spigot/Forge combination MCPC, which I got from Yive's Mirror.

Plugins like MCMMO and Worldedit seem to be working fine, but when I execute a command from Essentials I get the error:

"An internal error occurred while attempting to perform this command"

I have checked to make sure no plugins have gotten into the mods or coremods folders.

None of my plugins were working at all until I changed "custom-class-loader" to false in mcpc.yml

I have included a log of my server where I try to execute an essentials command, copied with Notepad++

I have the same error, sadly i think its an error with MCPC+

Cross-compatibility issue across your server jar and plugin.

Essentials is looking for data that isn't available within the Spigot API provided by your jar.
 Christian Prestridge: so we cant use essentials, i don't think
