 * I got a free host and am trying to install WordPress in it but when I got to 
   the installation step I got the following error:
 * > Fatal error: Class ‘WP_Widget’ not found in /home/a8329191/public_html/wp-includes/
   > default-widgets.php on line 14
 * I went to that exact file and line, checked if the class was defined, and even
   though I don’t know much about php there didn’t appear to be a problem.
 * Would really appreciate some help.
 * Thanks!

 * Check if your theme is compatible with WP 3.3. To check, you may try switching
   to the default theme (twentyeleven) for a moment by renaming your current theme’s
   folder in wp-content/themes. The idea is to force WordPress to fall back to the
   default theme to rule out any theme-specific issue.
 * -Ipstenu has put togather an extensive 3.3 troubleshooting guide. Please review
   it as well.

 * Checked the folder and there appeared to be two themes, “twentyeleven” and “twentyten”…
   Took “twentyten” out, re-uploaded that directory, and still same error. Doesn’t
   appear to be the problem.
 * Will take a look at the troubleshooting guide…
