Bukkit

What is the issue?
A new player to our server doesn't earn any exp when mining blocks but all the other players do. Any suggestions?

Please provide any additional information below.

Here's the permissions I set for everyone:
accept
experiencemod.info
experiencemod.rewards.block
experiencemod.rewards.bonus
experiencemod.rewards.brewing
experiencemod.rewards.crafting
experiencemod.rewards.fishing
experiencemod.rewards.smelting

This sounds like a permission problem.

Might be a stupid question, but - did you remember to reload the permission plugin when you added the new players? Just checking.

Also, are you using the default "presets.yml"? That might also be to blame.

If not, try enabling debug mode (write /experiencemod debug as an admin or into the console). Check the console output (or the log file) when these new players are mining blocks - are there any unusual messages appearing? Any errors? The lines should look something like this:

TIME [INFO] [ExperienceMod] Block mined by PLAYER: Spawned X xp for item ITEM_NAME.

In any event, looks like I found a bug when parsing mob names in the mob section. The fix should be in the next version (after 2.2.2), but in the meantime you may have to remove all the spaces from every mob name. That is, change cave spider into CaveSpider - basically, use CamelCase.
