I'm not sure what this is, but it looks wrong, so I'll report it: On the cited page, about 1/3rd of the way down I see this: =========== Suppose we are given a link diagram which is oriented, i.e. every component of the link has a preferred direction indicated by an arrow. Also suppose Failed to parse (Cannot write to or create math output directory): L_+, L_-, L_0 =========== where Failed to parse (Cannot write to or create math output directory): L_+, L_-, L_0 is in STRONG RED attributes. It might be an error from the article author's uploaded text; I can't tell by looking at the source. No other similar instances found in Bugzilla search.
Seems to be a common occurrence, purging fixes the problem. See reports: http://en.wikipedia.org/wiki/Wikipedia:Village_pump_(miscellaneous)/Archive_17#Failed_to_parse and http://en.wikipedia.org/w/index.php?title=Wikipedia%3AVillage_pump_(technical)&diff=264794554&oldid=264777926
Created attachment 5855 [details] Image of page displaying error http://en.wikipedia.org/wiki/Autoignition_temperature was also displaying this error until it was purged.
This was a bug introduced when fixing bug 16440 on r43965. Was fixed on r43966. http://wikitech.wikimedia.org/view/Server_admin_log/Archive_13#November_26
