Topic on Extension talk:Semantic MediaWiki

I'm attempting to install semantic media wiki but I'm having trouble with composer and making a working composer.local.json file. has anyone managed to get a working SMW instance working using the instructions on SMW website? if so could you give me a detailed instructions including the composer instructions. using composers website and SMW has either given me DB error messages or just failed to add the extension at all. any help would be appreciated.

A little more information would be helpful, like what os, db and php versions you are using. This means are you using supported versions of this software and do you have shell access. It should be no problem getting Semantic Mediawiki (SMW) running. First step is to get a clean Mediawiki site running with all extensions disabled when possible. Then "install" SMW using the documentation on the SMW website. Below our composer.local.json but you should start with only adding SMW.
