Yesterday I upgraded my blog, http://www.nunnayerbizness.com, to WordPress 2.9 using the automatic option.
All content had disappeared when I checked this morning. The header is intact as is most of the content of the left sidebar, but the sidebar ends with an error message: "Fatal error: Call to undefined function: __destruct() in /home/content/r/a/i/rainesdesign/html/NUNNAYERBIZNESS/wp-includes/default-widgets.php on line 735".
The main column and right sidebar do not display.
Also all links to WordPress.org on my blog's dashboard, display an error: "RSS Error: The data could not be converted to UTF-8".
Please help. While I have enough HTML to keep up some text widgets, I do not have the technical knowledge to track this down.
