Default folder/config -> nothing blocked.

You get the same error in CraftBukkit 2638?

yes the same message in both 2624 and 2638.

these messages apeer on start-up.

Can you give me the full startup log please?

none of the errors show on 326 -> blocks as normal. (just the event error is there).

Your server build is outdated. That's why.

I increased the required version of CraftBukkit to 1.4.7-R1.1 here: 7f4c2c8
