This error message seams to be popular again at the moment, so I guess its time to reeducate Joomla users and administrators on the cause of it:
This e-mail address is being protected from spam bots
If you get this message, then you are probably using a third party extension (like bfForms) and you see this message as an error. The solution is very simple. Joomla has a built in (a very basic!) plugin that replaces any email address in Joomla output with a snazzy javascript hiding technique to hide email addresses from spam bots.
All you need to do to resolve the error – is to disable this Joomla Plugin.
