The error is this: * `[14-Jun-2013 07:24:39] PHP Warning: htmlspecialchars() [function.htmlspecialchars]: Invalid multibyte sequence in argument in /home/ www/wp-content/plugins/crayon-syntax-highlighter/util/crayon_util.class.php on line 420` * That does not prevent the plugin to work correctly, but generates PHP errors and makes the javascript of my theme does not work. * Can you help me? * Thanks a lot. * [http://wordpress.org/extend/plugins/crayon-syntax-highlighter/](http://wordpress.org/extend/plugins/crayon-syntax-highlighter/) The topic ‘Problems with htmlspecialchars in crayon_util.class.php’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/crayon-syntax-highlighter_b0c4c0. svg) * [Crayon Syntax Highlighter](https://wordpress.org/plugins/crayon-syntax-highlighter/) * [Frequently Asked Questions](https://wordpress.org/plugins/crayon-syntax-highlighter/#faq) * [Support Threads](https://wordpress.org/support/plugin/crayon-syntax-highlighter/) * [Active Topics](https://wordpress.org/support/plugin/crayon-syntax-highlighter/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/crayon-syntax-highlighter/unresolved/) * [Reviews](https://wordpress.org/support/plugin/crayon-syntax-highlighter/reviews/) * 0 replies * 1 participant * Last reply from: [giltesa](https://wordpress.org/support/users/giltesa/) * Last activity: [13 years ago](https://wordpress.org/support/topic/problems-with-htmlspecialchars-in-crayon_utilclassphp/) * Status: not resolved
