I have a MediaWiki instance set up on a Heroku server with a Postgres database. I'm trying to import the Template: Infobox Fictional Location (and all the dependencies) from Wikipedia. I used Special:Export and Special:Import, but I'm getting "Fatal exception of type 'DBUnexpectedError'". When importing pages without templates, all goes well. Only when I include or try to explicitly export templates does it go poorly. I have Scribunto installed, and I *think* properly configured?
