E-mail address doesn't show up correctly inside the slider (Joomla)

Error

• Email address doesn’t display correctly in the slider.
• Usual message: This email address is being protected from spambots. You need JavaScript enabled to view it. and some html code is seen too.

Solution

This is happening because of the Extensions → Plugins (in older Joomla versions Plugin Manager) → Content – Email Cloaking plugin, or some other email cloaking plugin, so you should disable it.
