Hi there,
I’m not sure if this is a js thing or not but when using Twitter’s script to embed a Twitter feed in a Widgetised Sidebar element, the feed shows up in Chrome but not in Firefox.
I used the Custom HTML Widget to insert the script via the Appearance | Widgets menu, then in the Static Block for the footer, I used the Wigetised Sidebar to call the Footer Widget.
I even tried using a standard Text block and got the same result: The feed displayed in Chrome, but not in Firefox, which makes me think it might be a jscript / js error in the theme.
For what it’s worth, I tried this on my home computer and on my work computer via Firefox. Neither display the feed. Any help would be appreciated. Thanks!
