Post date translation

Hello,

Something very simple:

I can´t find where to change the easyblog post date:

English ("Posted on Friday....")
Spanish ("Publicado en Viernes....") IT SHOUDL be ("Publicado el Viernes") Need to change the "en" to "el" :-))

It is already in Spanish but I tried to find ths string in english and neither have found it.

Have check this files too:

/administrator/language/en-GB/en-GB.com_easyblog.ini - For administrative section
/language/en-GB/en-GB.com_easyblog.ini - For front end section

But I imagine those strings are in a easyblog theme translation

Thanks in advance.
