Thread:Project:Support desk/Internal error in Scribunto - Exception from line 167

I have recently upgraded MediaWiki from 1.24.1 to 1.24.2 last night, and initially Scribunto was working fine, but this evening the extension began to return internal errors for articles that use LUA modules, such as at https://nsindex.net/wiki/Minoa. I have already set the permissions of the executable in question to 755, thereby allowing all users to execute the binary that is required, but the error continues to persist.

Full details of error:

[e63a0872] /wiki/Minoa Exception from line 167 of /srv/data/web/vhosts/nsindex.net/htdocs/w/extensions/Scribunto/engines/LuaStandalone/LuaStandaloneEngine.php: The lua binary (/srv/data/web/vhosts/nsindex.net/htdocs/w/extensions/Scribunto/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic/lua) is not executable.
