Problem [SEVERE] issues =P

[Myobi]

Hello, I'm using FTB 1.4.7 Ultimate, around last week I started having issues with some severe errors...

First it was this:

9:34:01 CONSOLE: [SEVERE] java.lang.IllegalArgumentException: Slot 243 is already occupied by com.eloraam.redpower.world.BlockCustomLeaves@2ed14f80 when adding codechicken.chunkloader.BlockChunkLoader@2fba7483

19:34:01 CONSOLE: [SEVERE] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

I managed to "solve" it by deleting ChickenChunks from the mod folder.
Then I started to get this:

21:37:57 CONSOLE: to recreate an item id (13123 / shifted:13379) for an item which already exists as forestry.apiculture.items.ItemWaxCast@4a26ce7e. Check your config and resolve the conflict.

Any suggestions?
Big thanks =P

This is an Item ID conflict. Another mod that you installed is conflicting with ChickenChunks. Re-enable ChickenChunks and check out this thread about how to change Item IDs. Read the thread below from posts 4 - 7 for info on how to change it.
http://forum.feed-the-beast.com/threads/adding-ars-magica.19859/

Once you have new configs from changing the Item IDs correctly on the server. You will need to provide these configs to anyone else on your server for their client.

Big thanks mate, I'll give it a look ASAP.
Still quite weird since I've been playing with all these mods for over 1 month =S
