    I've never been able to click on the LaTeX quick commands and get them inserted into a post.

    I haven't tried it lately, though, on any other computer--just my iPhone just now.

    It seems to work fine when you enter the commands directly. Like grapes, I haven't had any success with entering commands by clicking on the LaTeX quick commands.

    For those of you wondering what LaTeX is all about, here's Coelacanth's equation in it's raw form. I've expanded the tex lead and trail with spaces so you can see how it's forumulated:

    [ t e x ]\int_{-\infty}^{+\infty}\frac{1}{\sqrt{2\pi}}e^{-\frac{x^{2}}{2}}d x=1[ / t e x ]

    Edit: We've been experiencing some problems with LaTeX recently, so I'm going to copy and paste Coelacanth's equation exactly to see if it produces the same results.



    Well, that works. So why doesn't this expression (without the spaces, of course)? \sum_{i=1}^{\infty}\frac{1}{i} Let's try it with the tex commands:



    Nope.

    Just checking LaTex implementation, because of complaints on other parts of the board.

    ETA: Change the setup slightly, 2 --> 3, for the one that works, above:


    ETTA: Same, this time:

    All four of the following examples should work without error:

    Features

    Creates a new BBcode, usually [TEX] (thought the tag name is configurable via the admin cp), which contents are processed thought LaTeX to generate image files. There are four calling modes:

    in-line mode. The image is included in the middle of the text, without line breaks. It tries to adjust the baseline of the formula by adjusting the vertical-align CSS property; the results aren't always perfect, but it does its best.

    displayed mode: The formula is displayed (usually centered) between two paragraphs.

    auto-numbering mode: The formula is displayed (usually centered), and numbered.
    NOTE: The auto-numbering depends on the CSS counter system, so some old browsers (most notably ie 7 and older) will show these equations untagged, like [TEX=null]. Don't blame me, blame non-standard compilant browsers.

    displayed with tag: The formula is displayed (usually centered) between two paragraphs, and tagged with the specific tag.

    Try this one:


    ([TEX]E= mc^3[/TEX]

    Nope. Here are the error messages returned:
    Warning: fopen([path]/vlatex/temp/3eb0c14588136ca38fcb790b9c07227a.tex) [function.fopen]: failed to open stream: Permission denied in [path]/vlatex/class_vlatex.php on line 276

    Warning: fputs() expects parameter 1 to be resource, boolean given in [path]/vlatex/class_vlatex.php on line 286

    Warning: fclose() expects parameter 1 to be resource, boolean given in [path]/vlatex/class_vlatex.php on line 287

    Also it seems to be double-posting replies.

    Note that may be helpful: Using Firefox-Linux(FC14) 3.6.24.

    LaTex didn't work, but the redirected image did. So to get LaTex into a post (for the time being), we could use

    [ i m g]http://www.codecogs.com/eq.latex?LaTexFormula[ / i m g ]

    where "LaTexFormula" is the LaTex "text". (Also take the blanks out of the tags.)

    it seems to be working now ... please confirm Tex is working !
