Thread:Project:Support desk/Lua error: Cannot create process: proc open(/dev/null): failed to open stream: Operation not permitted

I'm trying to get Infoboxes to work on my website, but keep getting the above mentioned error message in all my templates. I have given public_html/wiki/extensions/Scribunto/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic/lua a 755 permission, added:

require_once __DIR__. "/extensions/Scribunto/Scribunto.php"; $wgScribuntoDefaultEngine = 'luastandalone';

to my local_settings.php file but nothing works. Any ideas what might be the problem?
