 goldstern 2006-09-04 11:48:20 UTC I use Mozilla Firefox and Epiphany on Linux; I am a registered user on the Polish wikipedia. When I view the page http://pl.wikipedia.org/wiki/Operator_Laplace'a , there should be several formulas on the page, the first one is (in correct Latex) coded as :$\triangle f = div\ \overline{grad}\ f$ Instead of each formula, I see the following text: Parser nie mógł rozpoznać (Nie można utworzyć lub zapisywać w wyjściowym katalogu dla wzorów matematycznych): \triangle f = div\ \overline{grad}\ f (This is a Polish error message; "nie mozna utworzyc lub zapisywac w ... katalogu dla wzorow" means, as far as I can tell, "cannot create/write in the directory for formulas") Notes: 1. When I download the page with wget, or lynx -dump (as unregistered user), or w3m (as a registered user), I see the same error messages. Ditto when I use Mozilla firefox or Windows Explorer on Windows XP. 2. When I do any of the following, the error messages will disappear and the formulas are displayed correctly: a. click "edytuj" (edit this page), and then click the preview button "podglad" b. Change my "preferencje" (user preferences) to use some other language (specifically, I tried this with English, German, Hebrew), then go back to "Operator Laplace'a", and reload the page. (When I then change my language to Polish, and reload, the error messages come back.) 3. I had a similar problem on the English Wikipedia with the article http://en.wikipedia.org/wiki/Cichon%27s_diagram . The error message were in English (but I do not recall the exact text). However, when I did a "null edit" (i.e., I clicked the edit button, did not do any changes, then saved the article), all the error messages had disappeared, and the formulas appeared correctly. (Note: the null edit does not show up in the history of that page.) Hence: please do not edit the page, or else the error might disappear and will be harder to trace. Thank you for any help or advice. Martin Goldstern Brion Vibber 2006-09-04 12:43:52 UTC This will have been a cached error message from when there was a mismounted drive.
