I recently upgraded a 1.5 site to 3 something. Shortly after getting the extensions I needed I realized the email addresses were showing javaScript before the email link.

‘); document.write(addy837); document.write(‘<\/a>’); //–>\n “>the email address.

I found a thread about turning off email cloaking.

1. Login as Joomla Administrator
2. Extentions – > Plugin Manager
3. Check the plugin “Content – Email Cloaking” and click Disable

This issue stemmed from “System – AntiCopy” plugin that was installed. I needed the plug-in so the cloaking had to be disabled.
