the problem of dynamic sidebars not showing was answered with the advice: Try looking in functions.php for register_sidebar().
There was no further comments in that thread. I have the same problem, I checked in functions.php, as well as widgets.php, and my theme’s functions.php, and the only thing that shows up (global functions.php) is function register_sidebars($number = 1, $args = array())
followed by the arguments.
How do I know if I need the singular register_sidebar() defined, and how would I enter it into the funtions.php? In other words, how can I get those marvelous widgets that partially sold me on the theme to actually show up?
