Thread:Project:Support desk/Scribunto / Lua error: Cannot create process.

Problems installing Scribunto / Lua. Hi guys, another lua Scribunto issue. Please help! I have done my research and tried a number of things, see below. Looks like php related error.


 * CentOS
 * MediaWiki 1.20.2
 * PHP 5.3.23
 * Lua 5.1.4


 * 1) I have Chmod 755 extensions/Scribunto files and dirs.
 * 2) Chmod all lua locations /usr/bin/lua /usr/lib/lua
 * 3) Scribunto showing installed on Special:Version
 * 4) PCRE version 8.33

LocalSettings.php fragment


 * Phpinfo - disable_functions = no value
 * D/L Scribunto mediawiki again, re-installed, same issue.

ERROR - Lua error: Cannot create process. Backtrace: Thanks!
