 * The plugin causes this error after activated it:
 * `Warning: extract() expects parameter 1 to be array, boolean given in <b>/home/
   www/web333/html/sites/wp-content/plugins/sliding-widgets/sliding-widgets.php 
   on line 23`
 * WP 3.4.2 multisite installation, but plugin is only activated on 1 blog!

 * Possibly not multi-site compatible?
    I would suggest test it on a single site
   and see if you have the same issue.
 * Installer on my 3.4.2 perfectly.

 * Hi,
 * I’m getting a similar error right after activation:
 * Warning: extract() [function.extract]: First argument should be an array in /
   home/username/public_html/camvert/wp-content/plugins/sliding-widgets/sliding-
   widgets.php on line 23
 * Did anyone find a solution for this?
 * Thanks!

 * I found that if you go to Dashboard > Sliding Widgets > if
    Control box width
   Control box height is empty, you get the error. Put in some value, save and check
   your site again. Seems to have solved it for me.
