Need some specialized help or direction.

I have a 1.5.2 server with Bukkit 1.5.2 Rec Build. I use Essentials with Group Manager exported to McMyAdmin for simple User, Groups, and Permissions. I have heard in the past to switch to manual editing, but trying to go from McMyAdmin to Manual editing is confusing. I also can;t figure out how to get the paste bin to work so people can read my files.

Frankly I like McMyAdmin, but I cant seem to figure out whats going on now.

Here are my current issues I am unable to resolve.

1.
In the Main world users can use /spawn and /back
In the Nether users can use /spawn and can not use /back

2.
Monsters seems to have spawning or despairing issues. Sometimes there will be plenty of monsters, but when yu leave and come back at different times there will be no monsters.

3.
In the Nether Zombie Pigman seem to never despawn and seem to be auto-aggressive no matter what.

Please advise.

 

I can just advise you to switch to manual mode and move all your permissions from the world folders to your globalgroups.yml, if you run into issues merging the groups you may have to recreate the file (this may be easier!).

Which plugins do you use? Could you post your bukkit.yml on http://hastebin.com/, please? (just copy-paste, press the save-button on that website and copy-paste the URL you get there)

 

Thank you for helping.
