Changes

The import threw a 500 Server Error, but when I checked the Special:AllPages list of all pages in the Template namespace, the entries for the Template:Infobox, etc. pages show up but when I try to see them, I get another 500 Server Error.

I already had created a phpinfo page for debugging as described in [http://stackoverflow.com/a/10891317 this Stack Overflow answer]. (Note that $ php -i | grep 'what_you_seek' also works, but the command line interface or CLI may use a different configuration file.)
