I don't remember exactly how i did install the extension. My wiki is XWiki Enterprise 7.1.4 and the extension version was 3.1 Now I deleted the extension in Extension Manager, but it was like nothing happened. Just disappeared in Extension Manages' installed section. I now installed 3.3 version(using import and .xar file) and it's not working anyway. I must don't understand how xwiki works. Type this in source code mode: {{highlight language="php" style="monokai"}} <?php echo '<p>Hello World</p>'; ?> {{/highlight}} or use macro -> Highlight(highlight.JS integration) Check the page as user without "Administrator" and "Programming" rights. -- View this message in context: http://xwiki.475771.n2.nabble.com/Syntax-Highlighting-extension-problem-tp7… Sent from the XWiki- Users mailing list archive at Nabble.com.
