Support » Plugin: WP-KaTeX » I can not enter some mathematical symbols

• Hi there, thanks for providing us with support.

My problem with KaTeX is this.

When I try to write the following line (in HTML) for a new post on my web site with WordPress

[Latex] n \ leq x <n + 2 [/ latex]

I only get this on the way out

N \ leq x <n + 2 [/ latex]

That is, no mathematical symbol appears in the output article.

However if I write equations, such as:

[Latex] ax ^ 2 + bx + c = 0 [/ latex]

(\ Sum_ {k = 1} ^ n a_k ^ 2 \ right) \ left (\ sum_ {k = 1} ^ n a_k b_k \ \ Sum_ {k = 1} ^ n b_k ^ 2 \ right) [/ latex]

Yes they can visualize perfectly.

How is this resolved? I’ve tried everything and I can not fix it.

There may be a space after the slash in the closing shortcode tag. In my testing, including the space produces the same output as you describe.

@ascom You mean I should put [/ latex] instead of [/latex]?
I already did and the problem is not solved.
However when I write n \ leq x <n + 1 in the ‘insert code’ field of https://khan.github.io/KaTeX/ it perfectly displays the output expression.

I meant you should put $...$. In my testing, using this exact shortcode produces the desired equation output.

@ascom Thank you, I have tried with space and without space, and it is not resolved. Try to try it on another website. And then I tell you how it was

@ascom. I have done a clean install in WordPress (with Spanish language) in a new subdomain of my own domain. I installed the KaTeX plugin to avoid possible conflicts with other plugins. I installed a minimal theme, the simplest. And the problem persists.
Look, when I write in the input editor HTML
$x \leq y > z$

I get the following message KaTeX parse error:
Expected ‘EOF’, got ” at position 12: x \ geq y> z,

Code entered in html view

Code entered in normal view

Error message in the resulting post

Note: In all other cases, this plugin works very well. Thank you for creating it.
