Heiya Richard,
I would suggest to first upgrade MediaWiki to MW 1.27 and deal with
adding further extensions like Semantic MediaWiki etc. to it in a second
step.
If you are using shared hosting when it might be a bit more complicated
to install Semantic MediaWiki since it is best installed with Composer.
However there is also a tarball provided.
Just have a look at [0,1] for infos on Semantic MediaWiki.
Cheers Karsten

Not yet. I hadn't learned about semantic mediawiki until after I
created my installation.
