I recently set up a WordPress 3.0 site (www.booksnbots.com), and my web hosting provider is 1&1.
When I go to my dashboard, the "Right Now," "Quickpress," "Recent Comments," and "Recent Drafts" widgets work/load fine.
However, on my dashboard the "Incoming Links," "WordPress Blog," "Plugins," and "Other WordPress News" widgets do not load. Their status bars just keep saying, "Loading..." Their configurations appear to be fine.
There is one thing I've thought that might be causing this problem. When I was designing the site, I used a temporary domain name (I say "temporary" only in the sense that it was a domain name that I didn't intend to use for the final site). When I was finished, I switched everything over to the final domain name, booksnbots.com. I've had to manually switch some things over to booksnbots.com, and I used the Search & Replace plugin to switch all occurrences of the original (test) domain name to the final domain name.
Dashboard still doesn't work properly, and I've also lost the ability to automatically install updates for plugins (or anything else for that matter). I'm having to manually intall everything now.
Any help would be greatly appreciated.
