This template has two problems: a script error is hiding the link to the documentation, and the link to Wikipedia should be `https:`, not `http:`.
Template talk:Work
This template forces the title to be italic, which means that any further attempts to change the title produce a warning message about how the new custom title overrides the old one. I discovered this when trying to give iAntiVirus a lowercase i as it should have. I don't see any evidence of a parameter in this template that allows a custom title to be placed directly in the template's own iteration of DISPLAYTITLE, and I think such a parameter is necessary. Admittedly I can't make head or tail of the collection of Lua modules that went into it, though.
I've had the same problem with a page I made (fault), and an edit by Looney Toons fixed it.
Adding {{DISPLAYTITLE:''[TitleHere]''|noerror}}
hides the error message.
Ah, you beat me to the answer. <grin>
Good, we need as much knowledge-sharing as possible.
