Errors in Dashboard

When I went to update this plugin, thankfully on a local version of the site, I got a number of errors.

Here’s what I saw when I went to update other plugins:

Strict Standards: Declaration of Conditional_Widget_Walker_Category_Checklist::start_lvl() should be compatible with Walker::start_lvl(&$output, $depth = 0, $args = Array) in /Applications/MAMP/htdocs/site/wp-content/plugins/conditional-widgets/walkers.php on line 42

Strict Standards: Declaration of Conditional_Widgets_Walker_Page_Checklist::start_lvl() should be compatible with Walker::start_lvl(&$output, $depth = 0, $args = Array) in /Applications/MAMP/htdocs/site/wp-content/plugins/conditional-widgets/walkers.php on line 76

Hope this gets fixed soon so that I can update.
