Thread:Project:Support desk/Problems with Ambox/reply (3)

Hello still here! I changed my host because the previus one give me to much problem. Now I have an host with mediawiki 1.21.1 installed http://alfoxwiki.altervista.org/. But: Fatal error: Call to a member function loadString on a non-object in /membri/alfoxwiki/extensions/Scribunto/engines/LuaCommon/LuaCommon.php on line 549
 * I export from mediawiki Template:Ambox, and import in mine but the import failed because it wants Scribunto
 * installed Scribunto (as in documentation: put the file in the Extention folder, and add 2 line in )
 * re-imported Template:Ambox with no error. But if I go in http://alfoxwiki.altervista.org/index.php?title=Template:Ambox this is the error:

I tried also to import Template:Infobox from wikipedia. Import finish without errors but as you can see here http://alfoxwiki.altervista.org/index.php?title=Template:Infobox the Script daesn't work.

Why?

Thanks for helping
