# Plugins won't coexist

 * Hi all!
 * I am using these 2 plugins:
 * HTML Page Sitemap
    [http://wordpress.org/extend/plugins/html-sitemap/installation/](http://wordpress.org/extend/plugins/html-sitemap/installation/)
 * SyntaxHighlighter Evolved
    [http://wordpress.org/extend/plugins/syntaxhighlighter/](http://wordpress.org/extend/plugins/syntaxhighlighter/)
 * When activating SyntaxHighlighter, HTML Page Sitemap won’t render anymore (no
   output created).
 * Any idea as to why this may happen?
 * It’s weird because I’d assume these aren’t really playing in the same space…
 * Help is appreciated!
 * Have a good day!

 * It’s the other plugin’s fault. Dashes aren’t allowed in shortcode names.
 * When my plugin registers the `[html]` shortcode, WordPress gives the
    `[html-
   sitemap]` shortcode to my plugin for processing due to the dash.
 * Edit their plugin and remove the dash and it’ll work fine. 🙂
 * _I’ve updated the Codex to reflect that dashes shouldn’t be used. It was actually
   using a dash in the example! 🙁_

 * Woah!
 * Such a simple fix, and it works beatifully.
 * Glad this has been added to the codex, that way some headaches will be saved 
   😉
 * Thanks Alex, and great work with the plugins (I use quite a few that you have
   built)
 * Have a good day!

 * I’m fixing html-sitemap plugin to use html_sitemap and htmlsitemap as shortcodes.
   I’m leaving html-sitemap for backwards compatibility and will link to this thread
   in the readme so folks know why it was changed.
 * I even named the plugin with a dash based on the shortcode example having a dash,
   I assumed back in 2009 that was recommended way of naming shortcode plugins.
