Rick, use your admin's Tools->Developers Tool Kit and search for $template->get_template_dir. What you're looking for are (poorly coded) constructs that look like:
Code:
<?php echo $template->get_template_dir('',DIR_WS_TEMPLATE, $current_page_base,'jscript') . '/css_browser_selector.js';
See how the first variable is an empty string? You'd change the above to
Code:
<?php echo $template->get_template_dir('css_browser_selector.js',DIR_WS_TEMPLATE, $current_page_base,'jscript') . '/css_browser_selector.js';
to correct the error. Repeat for each instance found.
