Created attachment 14663 [details] notice how it reads "aligndat" in stead of "alignat", but this isn't the case when editing the page. Parsing mathmatical functions in Tex fails sometimes for an unknown reason. I checked on different computers and browsers and I asked other people on different location to check this for me, all got the same errors. Namely: Parsing failed(unknown function "\begin"):... At first glance it looked like a syntax error, but when editing the page the syntax looked perfectly fine. Weirdly enough, not all pages are affected and just re-saving the pages in question solved the issue, but the problem persists on many other pages. e.g.: https://no.wikipedia.org/wiki/Line%C3%A6rt_ligningssystem https://nn.wikipedia.org/wiki/Line%C3%A6rt_likningssystem https://gl.wikipedia.org/wiki/Sistema_de_ecuaci%C3%B3ns_lineais I also found similar problems in wikibooks.
I assume the screenshot comes from http://nl.wikipedia.org/wiki/Stelsel%20van%20lineaire%20vergelijkingen Please try to ?action=purge the page - see https://en.wikipedia.org/wiki/WP:Purge All three Math items on display correctly for me by PNG and MathJax. https://nl.wikipedia.org/wiki/Speciaal:Voorkeuren#mw-prefsection-rendering-math
Yes, sorry I forgot to specify where the screenshot came from. The page now renders correctly, but it was one of the pages I re-saved. Did you check the other links I mentioned, do those render correctly on your end? If not, I can hardly purge all pages where this problem persists, can I? Is there no global solution? Kind Regards, Oculum
Which of the three available settings on https://nl.wikipedia.org/wiki/Speciaal:Voorkeuren#mw-prefsection-rendering-math do you use?
I use PNG most of the time because its faster. I've just tested with mathJax and it renders correctly. But PNG still gives me errors on e.g. https://nn.wikipedia.org/wiki/Line%C3%A6rt_likningssystem Anyway, like I mentioned in the first post, it seems like I'm not the only one experiencing this problem and as far as I know it's impossible to change the render mode if you don't posses a wiki-account, what can other people do to fix this?
I wonder if these problems are still the aftermath of bug 60997 - if purging does not help it is worth to investigate, so I recommend to purge first by reloading the page with "?action=purge" attached to the web address.
Ok, purging seems to work on all occasions, I'll guess I'll do this everywhere I come across this problem, there are however a lot of pages in a lot of languages where I find similar errors, so it might take a while before everything is solved. Anyway thanks for your time. Kind regards Oculum
Alright :)
