Bug Weird LaTex bug

  1. Dec 12, 2008 #1
    I'm getting this weird LaTex bug that is really messing with my posts.

    Sometimes when I use the tex tags, I get this weird problem that no matter what I put inside them, the post will always display the a certain equation inside of the tags.

    For example:

    I am trying to edit my signature (writing my name in greek letters), however, no matter what I put inside the tags (anything at all), the only thing that will come up as a result of my tex tags will be:

    [tex]\rho=\sqrt{4az_0}[/tex]

    The problem is on/off (for example I don't seem to be having the problem with this particular post), however, when it ocurrs, it is very irritating.

    Does anyone know what is happening?

    Here is a screenshot of the problem. It shows the wrong result coming from what I typed in the edit box (the preview in the picture is directly off of what is written in the edit box and no changes were made).

    You tried all the usual stuff - clearing cache, refreshing window a half dozen times, etc?

    Yeah. The equation that it keeps displaying is from a while ago too.

    I don't believe the LaTeX feature is designed for signatures. Partially because the post id is used for part of the images name. Obviously there is no post id when making a signature.

    But I've had the same problem making regular posts as well.

    I have the same problem. It first appeared when I entered to Greg's blog. I almost got a heart attack when I saw something written in Latex : it was exactly what I wrote in a homework thread!!! I was thinking "what a coincidence!!" but then I realized further on the page other formulas that I wrote and started to understand what was going on : it's like whatever there is written in Latex, it will always appear something you saw before, or maybe something you wrote in Latex before. It happens since more than a week (maybe even 2 or 3 weeks) at least.

    I think you only get the wrong image when you mess up the LaTeX code (and apparently when you try to use LaTeX in signatures). Example:

    You're wrong. It might appear when you enter a wrong Latex code but it's not the cause. I don't think Greg's blog contains only wrong typed Latex code.
    Check out the first post on this thread, Math Jeans typed \sigma and what appeared was \sqrt{4az_0}. Both are well typed Latex code.
    Hence that's a really strange bug. :rolleyes:

    Math Jeans, if you just need Greek characters you can copy-and-paste from here:

    FYI, some characters look much better in boldface Times New Roman font

    I really do think all of these kinds of problems are cache issues in the browser, but I don't know why some people seem to have recurrent problems and many others never have any. I'll try to reproduce some of these bugs myself, at least.
