LaTeX wrong on several websites

[Omega0]

I am pretty disappointed that several websites like physicsforums.com do partly not show correct LaTeX content. So please let me know if I am doing something wrong. My standard is Windows 10 with Chrome. Same problem for Edge. For so many years I hadn't a problem but now that appears.

Firstly, we use MathJax. But this means only that we cannot use all LaTeX commands. Secondly, do you have an example of what does not work?

Have you checked the LaTeX Guide at the bottom left of the Edit window? Maybe you can see what the issue is by looking through that Guide?

Sure, here the example for physicsforums.org:

As you can see it switches between different fonts and even messes up the information $\pi/2$ somehow... that is brutal, simply unusable.
I am not using "all LaTeX commands", just a few. This horrible result is the same for any of my computers, even for my Android tablet.

%%\pi/2%%

What are the % things?

What are the % things?

sorry, $\pi$ inline LaTeX.

$\frac{1}{2}$ let us see... $$\frac{2}{3}$$ next LaTeX test

I meant a testable example. A screenshot isn't helpful.

I know that the preview function has some problems in case the post contains a quotation. Your screenshot looks as if the symbols have been inserted via the table of symbols and not as TeX commands. And I also know, that after an edit, the commands aren't interpreted again unless one updates the page.

For me the LaTeX looks like in my screenshot. If it looks for you different, let me know. Actually I am playing with cleaning my browser cache but nothing seems to work so far. Test: $0\leq\phi\leq\pi/2$ etc. Test: $$\theta(a)=\frac{\phi}{\pi} \sin(a)$$

As if I would need to "reininstall my browser LaTeX"

I looked at it with my "edit" power to check the source and all those symbols haven't had LaTeX tags, hence it cannot be interpreted as LaTeX.

You can use the "Reply" link to also see the source characters. They look okay to me I think...

Have you any idea how it comes that my LaTex input isn't interpreted as LaTeX? I mean it is not my fault or is it?

Edit is far better! I can cancel "edit" but I cannot cancel "reply". And if I look for too long, it is in that damn cache and shows up again when I expect it the least.

Excellent point.

It looks as if it was your fault because it was just 0≤Θ≤2π. I used the table of symbols in this case, instead of ##0\leq \theta \leq 2\pi##

P.S.: This can happen if the text is copied from another text by Ctrl+C.

How did you do that to get the latex source to appear in your post instead of the latex render?

I tried PLAIN tags, but that did not work, so I used the good old color code:
#[COLOR=rgb(0, 0, 0)]#[/COLOR]\sqrt{2}[COLOR=rgb(0, 0, 0)]#[/COLOR]#

Of course, I didn't type that. I marked one of the two sharps and colored it black with the color icon.

Thanks! I would never have thought of something like that.
