Q. Nothing happens after I install this plugin. I can still use x-ray without any problems.

A1. You should be warned at login if you are bypassing Orebfuscator. This is caused by the bypass checks done on OPs and players with permission "Orebfuscator.deobfuscate". You can use commands "/ofc disable op" and "/ofc disable perms" to disable these bypasses so that you can see the obfuscated world.

A2. The default configuration does not prevent x-ray TEXTURE PACK. Some configuration change needs to be done before it can prevent texture pack X-RAY. Read more abouttexture pack X-RAY at How to properly configure Orebfuscator

A3. Orebfuscator fight x-ray in a way that efficiently prevents people from seeing the location of blocks (ore, mossy cobble, etc), which means Orebfuscator is only effective against hackers who use x-ray to find ORE and other blocks. WARNING: Orebfuscator does NOT hide caves. It's technically impractical to do so (would take too much CPU).

Q. java.lang.OutOfMemoryError: Java heap space

A. Situation 1: Your server is very low on memory. ADD MORE MEMORY TO JAVA by adding the switch -Xmx#M or -Xmx#G (Replace # with desired number)

ex: "java -Xmx4g -jar craftbukkit.jar" will set heap size to 4GB

A. Situation 2: Your server has lots of memory but it still crashes with OutOfMemoryErrors:

TRY THIS:

You can try adding "-XX:+UseParallelGC" OR "-XX:+UseConcMarkSweepGC" (not both) to the command line of the server startup script if you are experiencing OutOfMemoryException.

This changes how Java free memory and allows memory to be freed more often in some cases, resolving is less crashes.

Q. Lag, help!

A1. Try updating This plugin to latest version and Craftbukkit to latest RB. If you use Spout, make sure to use the latest recommended version.

A2. Your server is incapable of handling more calculations. This plugin indeed takes more computational power than just the default minecraft. Despite being optimized again and again throughout its history, this plugin still uses considerable amount of CPU. An appropriate server with a fast CPU should help.

Q. I have problems with NoLagg plugin

A. Update to the latest version of NoLagg should fix the issue. If it doesn't, please give a shout to both me (lishid on bukkit.org) and NoLagg's creator BergerKiller.

Q. Players report seeing fake ores!

A1. In most of the cases, they are x-ray hackers who tries to get the server admin to remove the anti-xray mod so they can start hacking. Make sure you (the admin) confirm the problem yourself and/or by other trusted members of your server.

A2. You should first attempt to clear cache (with command "/ofc clearcache") and ask everybody to logout/login. If that does not fix your issue, ask about it on the forum.
