# Long post fails to render

In one MathOverflow answer by me, the MathJax code added latest fails to render correctly. Instead, one $ tag is ignored and for the rest on the line, code inside $ tags is rendered as if outside $ tags and text outside $ tags is rendered as if inside $ tags. Is it because the post is too long or contains too much MathJax code? ## 1 Answer I think it was just an oversight - unpaired curly brackets. Putting $V_{i(g)(\kappa)}^M=V_{i(g)(\kappa)}^N$ $$V_{i(g)(\kappa)}^M=V_{i(g)(\kappa)}^N$$ works as expected, $V_{i(g)(\kappa)^M=V_{i(g)(\kappa)^N$ does not render: $$V_{i(g)(\kappa)^M=V_{i(g)(\kappa)^N$$. I have edited the post - I hope I haven't overlooked some other problem. You can compare revision 4 (your version) with revision 5 (my edit). Revisions 4 contained: and since$V_{i(g)(\kappa)^M=V_{i(g)(\kappa)^N$,$\kappa$is$i(f)(\kappa)$-extendible in$M\$.

As a side note, when somebody runs into problems with MathJax when posting or editing, they could try asking in the MO editor's lounge or in the Mathjax chatroom. However, both of those rooms are visited only by a few users - so on meta, such question will get noticed faster (and it will get more eyes on it).

• Thank you. I found another place where I forgot a bracket. Sep 3, 2022 at 21:19
