I do see the email!

It seems to be caused by something in your template. Check the URL using the Joomla core protostar template...

Ok, happy you found the cause.

The email address is not in your html output. Everything seems to be working fine.

Are you looking in the actual output html (source)? Or are you using the element inspector?

Please try the latest development version from:

Issue was with the extra spaces inside the href attributes.

Because that is what the javascript turns the obfuscated code into. That's how the whole thing works.
Obfuscate the email addresses in the output. But make it work in the browser.

Email obfuscation is never 100% watertight. But 99.9% of the bots take the easiest road, and that is combing through html.
Fully rendering a page including the javascript and css and then trying to read the dom, is not a light process. So it is not impossible, but not practical for bots.
