I followed the steps, however I appeared the following errors:

www.testeo.servidoronline.net/fullsample/

What I did was:

1. Update to version framwork yt 3 of Joomla, however did not work.
2. Recode index.php and yt_template.class.php files, but don´t work.

What should I do now?

Dear Sebastián Pizarro,

Please go to Administrator >> Global Configuration >> Server >> Error Reporting >> select None

Thanks!

Thank you very much, but does not load the main images of the template. What do we recommend?
