Thread:Project:Support desk/MediaWiki Error: Lua error: Internal error: The interpreter has terminated with signal “11”

I have a MediaWiki deployement at: http://wiki.tankpedia.org/

My MediaWiki version is: 1.21.1 PHP: 5.3.24 MySQL: 5.1.69

I have been importing templates from Wikipedia and am receiving a Lua error for the Convert template; the error is: Lua error: Internal error: The interpreter has terminated with signal "11".

The error can be seen here (you have to click on one of the 'Script Error' messages): http://wiki.tankpedia.org/index.php?title=M2_Light_Tank

The Scribunto deployment this is dependent on is `chmod` to 755.

The following error also appears on the same page: > Expression error: Unrecognized punctuation character "["

Research online suggests this relates to the ParserFunctions extension however it is installed; I even added the following extra line in my config file and it did not help: >$wgPFEnableStringFunctions = true;
