Hi Maribel,
May I know which extension you are referring to? Did you install the language inside the extension itself? For example Languages>Spanish>Install

Can you also provide some screenshots of your issue in the frontend so I can better identify the parts of your page that is still in english? Thanks.

The extension is Easy Social and i did the installation with that error.

Hi Maribel,
I have installed Spanish on EasySocial(85% translated) and set the default site language to Spanish in Joomla's language manager.
This is what I see in EasySocial frontend(http://take.ms/rH8xE).
Does this solve your issue? Check it out and let us know, thanks.

Thanks again!
