# Why is LaTeX not displaying correctly? [duplicate]

This question already has an answer here:

In this answer On a proof of the existence of tubular neighborhoods. and Neil Strickland's answer here Is the counit of geometric realization a Serre fibration? the laTex is not displaying correctly (in Firefox version 21.0). Oddly, it looks fine after I click the edit button. Anyone know what's going on? In the second case, I'm pretty sure it looked fine earlier today, before the upgrade.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

• Oh, I didn't see this. I asked essentially the same, with another example. – Andrés E. Caicedo Jun 25 '13 at 4:53
• I have been using backticks a lot in answers, questions and comments and now they render incorrectly. Will it be possible to fix this problem automatically? There are too many of them to do it by hand. – Karol Szumiło Jun 25 '13 at 10:21
• If I remember the original discussion, the backticks were supposed to be fixed automatically. Did something go wrong? – Emil Jeřábek Jun 25 '13 at 11:48
• For example my answer mathoverflow.net/questions/104866/… is completely messed up. I'm not sure whether this is a problem with backticks. I think I used them when I wrote this answer but I don't see them when I look up the source now. – Karol Szumiło Jun 25 '13 at 18:25

Weirdly, I managed to fix Neil Strickland's answer by editing it to remove whitespace from the end of the post.

I fixed your answer by removing the backticks and changing the backslash-brackets to double-dollar-signs. I think the new system doesn't play nicely with backslash-brackets.

EDIT: See also the discussion here.

• Thanks for fixing it! – Dan Ramras Jun 26 '13 at 4:52

Here is another question which doesn't display correctly (but whose preview on editing does): Algebraic closure as a fibrant replacement?

• Apparently the underscore in the subscript \mathfrak{m}_i was interpreted as the beginning of an _italics_ sentence. I was able to fix it by surrounding the subscript by braces, i.e., writing \mathfrak{m}_{i} instead. – Martin Jun 25 '13 at 16:19
• @Martin: Can you try your magic on this question, too: mathoverflow.net/questions/134142 ? The problem seems similar. – Francois Ziegler Jun 25 '13 at 17:51
• @FrancoisZiegler: The magic is to make any sort of a trivial edit to the post (such as adjusting whitespace), then it takes care of itself. – Emil Jeřábek Jun 25 '13 at 18:16
• @Emil: I see. Thanks for fixing it! – Francois Ziegler Jun 25 '13 at 18:19
