I know this is probably over-asked, but I'm running out of time. I'm having trouble finding information on creating Templates, specifically for Infobox, for a private MediaWiki site. I understand the hesitation to offer the information, due to the chance someone may take it as license to make changes to public sites. However, as a private site, I have some specific needs.
I attempted to follow the Import/Export process spelled out here (below), but I get a Server 500 error when I do the import. (The XML appears well-formed to me, though.)
Manual:Importing Wikipedia infoboxes tutorial
Any direction that can be provided would be appreciated.
MediaWiki version 1.28.0 (release 83)
PHP version 5.4
MySQL version -- unsure
My proof of concept site (my testing for compatibility with the full need) is lisbona.trianglemoon.com
