I’ve copied the ExampleExtension code found at https://www.mediawiki.org/wiki/Manual:Parser_functions and find that it doesn’t work with my REL1_33 wiki. I’m not getting any error message, it’s just that the parser tag is output as if the extension isn’t installed. (Yes I’ve made sure to create the ExampleExtension.i18n.php file.) See https://slicer.qualitybox.us/wiki/User:Grundlett/Sandbox for example.
Does anyone have this example working? I’m trying to create a real parser function extension to transform XML with XSL and have the same problem as the example (fails silently outputting as if the extension is not loaded).
