Support for the latest build of L2J Server, get help here with installations, upgrades, problems.
Do not post bugs reports here, use viewforum.php?f=77 instead. There is no support for other server builds than the official provided by l2jserver.com
Those are warnings, not errors, you can ignore them.
Devs should fix them though, these are very simple things.
@P.S. - just use the /trunk/L2J_Server[|L2J_DataPack] instead of /branches/unstable/..., obviously.
If you have problems, FIRST TRY SOLVING THEM YOURSELF, and if you get errors, TRY TO ANALYZE THEM, and ONLY if you can't help it, THEN ask here.
Otherwise you will never learn anything if all you do is copy-paste! Discussion breeds innovation.
