This message is occurring no matter what I do. I've made sure that the path is indeed correct, and it is. This is my LocalSettings.php:
$wgScribuntoEngineConf['luastandalone']['luaPath'] = 'C:\xampp\htdocs\w\extensions\Scribunto\includes\engines\LuaStandalone\binaries\lua5_1_5_Win64_bin\lua5.1.exe';
I can't find anything wrong with this, and I can't find anything else by myself, so I'm asking for help. Any ideas?
