I updated the plugin to version 10.0.1 yesterday and I’ve also a problem with \neq in my blog… the code is simply [latex]b \neq 0[/latex]. The odd thing is that the formula is shown differently in two pages differing just for the language: in the Italian page it works fine with both Firefox and Chrome, whereas in the English page it works with Chrome but not with Firefox.
Italian page (correct behavior): https://dimostriamogoldbach.altervista.org/definizioni-simboli-teoria-dei-numeri/
English page (not correct with Firefox): https://letsprovegoldbach.altervista.org/definizioni-simboli-teoria-dei-numeri/
In the second case with Firefox 65.0.2 (64 bit) I see a Unicode symbol which is non correctly rendered:
https://letsprovegoldbach.altervista.org/wp-content/uploads/2019/03/Schermata-da-2019-03-24-07-00-56.png
The pages are on the same hosting, both running WP 5.0.3 and KaTeX 10.0.1.
I can’t figure out what’s happening. May you help?
Thank you very much,
Simone
