HudsonValleyWebDesign tks but i manage to do a workaround. Still have to see what was causing the issue.
Stanordan, I have this issue but i manage to make a workaround. Dont know why it happens but i copy another theme i was making and just changed the theme slugs. Now all is fine. Dont know why, the from functions.php is exactly the same. Now when i install the new theme the sidebar gets registred and appears with the default widgets inside. Im new to wordpress developement but i guess this is the default behaviour of wordpress when a new sidebar is registred right? nedd to figure out why the sidebar wasent working.
anyway tks =)
