On the PT article about Orc (http://pt.wikipedia.org/wiki/Orc) there was an error after put the tag, "Cite error 4; Invalid call; no input specified".
RESOLVED WONTFIX, it's supposed to do that.
May be it should be silently ignored instead of displaying the error message. In some cases, the content of a ref tag may be empty if it is generated by some variable template. Workaround: use {{#if:{{{1|}}}|<ref>{{{1}}}</ref>}}
