strange post in home page, please advice!

I am unable to get rid of a post in the home page. I attach a file with the screen image. The post says: "Bienvenidos a la Portada" (my joomla is in Spanish)
I went through everything: checked the menus and deleted all but the main one, checked modules, checked all articles, nothing there!... This post came with joomla and I can't find where or what is it so that I can delete it... I already cleaned the cache as well.
I can´t install the demo version of my template (youzine) because it comes with joomla in English and there are features I can´t change to Spanish (like the results in polls f.i.)

Any ideas as to what could I have not checked yet in order to get rid of it?

Thanks a lot for your help, I appreciate it!

Hi Eva

Did you check the Home menu link if the 'show page title' is on?

I don't understand why you can not use the demo in english, then download the spanish language pack for the site (or what language you need) and then make it the default language..?
The language pack is supposed to translate all things default in joomla such as the polls etc..
Results of polls I thought you could translate by using joomfish?

Thank You So Much. I didn't know there was a language pack, I installed it and now I can use the demo that comes with youzine, it even translated the results of polls. What a relief!

Thanks.
