In this thread hard coded widgets can be removed from sidebar.php.
I have GridMarket 1.4.9 and tried removing the code but the widget still appears. I tried it in wp-content/themes/framemarket/sidebar.php and also gridmarket's sidebar.php at the same location but the widget still displays. I refreshed my page several times and do not have a cache plugin. Any suggestions on how I can remove it? It displays for a logged out member only.
