I just setup a new WP install on my VPS, and noticed that the Other WordPRess News dashboard widget is giving me an RSS Error.
RSS Error: The data could not be converted to UTF-8. You MUST have either the iconv or mbstring extension installed. Upgrading to PHP 5.x (which includes iconv) is highly recommended.
I have other WP installs on this same server, and Apache configuration, and the Other WP News dashboard widget seems to work for them.
Given that these widgets use SimplePie to grab the RSS feeds, why would it be working in one widget area but not another on the same page, when both of this widgets work on a different install of WP on the same server?
