Support » Plugin: SyntaxHighlighter Evolved » Serious flaw with HTML and syntax highlighter.

  • In WP 3.7.1, there is a serious flaw. The shortcode does not support HTML very well.

    For example, if we type the following in to Visual editor:

    [code language="html"]
    <input type="checkbox" id="cbox1" />
    <label for="cbox1">Option 1</label>
    <input type="checkbox" id="cbox2" />
    <label for="cbox2">Option 2</label>
    <!-- ...and so on -->

    [Moderator Note: Please post code & markup between backticks or use the code button – not the blockwquote button. Your posted code may now have been permanently damaged by the forum’s parser.]

    The output is such:

    & lt ;blockquote>& lt ;input type=”checkbox” id=”cbox1″ /& gt ;
    & lt ; label for=”cbox1″ & gt ; Option 1 & lt ; /label & gt;
    & lt ;input type=”checkbox” id=”cbox2″ /& gt ;
    & lt ;label for=”cbox2″& gt ;Option 2& lt ;/label& gt ;
    <!– …and so on –>

    It appears that the plugin is printing the escape sequences for the HTML characters.

  • as WordPress support forums seem to have a hard time with escape sequences, here’s what it looks like in a picture.

    Update:</b> Very strange. It seems that the issue is confined only to preview mode. When I hit “publish”, it displays as normal.



    I have the same issue.

    Only option for me is to edit the post in Text mode

    I am having the same issue too when posting code from Windows Live Writer using the Source Code Highlighter Plugin for plugin ( This worked fine in the past, and only recently started converting things like double quotes to "&. Solution for me to use edit the post in the WordPress editor right on the site and convert the characters back to what they should be.

    I hate to say it, but this bug is serious enough to make me switch syntax highlighters. Anytime I post HTML, XML, XAML, or any other language that uses the less-than/greater-than signs or double quotes, I have to go in and manually edit all of those code samples again directly on the WordPress site in Text mode. Looks like this product hasn’t seen an update in 9 months. I hope it’s not dead, as I really like SyntaxHighlighter Evolved 🙁

    A bit of bump for this thread but I found basically the same error.

    For me when viewing of a page that is using SyntaxHighlighter Evolved the entire page’s source code is full of escapes characters such as & lt; and & gt;.

    This is messing my usage of Autoptimize on this page and as such no styling gets applied to the code on the pages using SyntaxHighlighter Evolved. Unfortunately I can’t think of any way to deal with this. Anyone else have any luck?
