I thought this was a pretty strange issue as StackableItems is ONLY having a problem with bPermissions. When tested with PermissionsEx (or any other plugin for that matter), the plugin ran fine.

I was using CraftBukkit Beta Build 1.4.7 R0.1, along with StackableItems v.0.9.1 (the new update didn't fix it) and bPermissions v2.10.3.

Oh, and as an extra note, bPermissions didn't cause any other plugins to error upon start up.

Here was my error from before (should I just post a PasteBin link?):

Error occurred while enabling StackableItems v0.9.0.1 (Is it up to date?)

Can you post an error using the latest version? Some of the code has changed, and it may not be exactly the same problem.

Also, pastebins work fine as long as you set them to never expire.

I'm glad to hear that it is working. Let me know if you have any other issues.

Hmm, this is strange, the issue has just suddenly vanished. Sorry for wasting your time. I suspected that this wasn't an issue of permissions configuration, because I would've noticed other problems too, but I did not.
