The afterDisplayContent event makes sense in Article view only so you need to check /html/com_content/article/default.php for it.
sorry but my programming skills are limited
are you telling that the line must appear into default.php??
thank you anyways
and I´ve realised that I have made no changes to this file, in fact there´s no file since the original components/com/content/views/article/tmpl/default.php is used insted
maybe I´m not explaining what I want, please take a look at
http://www.opticos-optometristas.comok, so I want the add comment to appear next to "leer mas (that means continue reading)"
