HI folks,

I am indeed new to Mediawiki. I have played with MW these past two weeks and am blown away by it's complexity and its incredibly beautiful simplicity. For my own education I have install MW a number of times including the stable release as well as the core.git. I am currently running both versions on the server. I am running MW on Ubuntu 12.04 server. CLI only, no GUI desktop. It is running apache2/php5.3.10-Ubuntu pkg / MySQL5.5.23 / Pecl and all the normal and require php5 modules. Using memcaching as well. This is a physical server and not a VPS.

The issue I have had is the Lua engine popping an error on Module:Authority_control script. I have turned on lua error logging and tailing the log file produces nothing. Here's the back trace in the script error from the page in question:

This is the code in the page that triggers the "script erro" message in the page.

{{Authority control|VIAF=40172183|LCCN=n/79/114053}}

Lua error in Module:Authority_control at line 179: attempt to index field 'wikibase' (a nil value).

Backtrace: (tail call): ? Module:Authority_control:179:in function "chunk" mw.lua:553: ? (tail call): ? [C]: in function "xpcall" MWServer.lua:73: in function "handleCall" MWServer.lua:266: in function "dispatch" WServer.lua:33: in function "execute" mw_main.lua:7: in main chunk [C]: ?

I have installed Wikibase and run the update.php. Added the required lines in Localsettings.php. Module:Authority control is installed.

I am sorta kinda at a loss as to where to look. If anyone could point me in the right direction to research the error, I'd certainly be appreciative.

Chap
