Karma Update problem

I received this fatal error after an update of Karma Theme. Can anyone please help as it has been working great for some months now. This patch for our multi language site is essential and we need to resotre it.

Thanks in advance. Chris Fatal error: Call to undefined function language_selector_flags() in /home/content/07/9976107/html/wp-content/plugins/wp-php-widget/wp-php-widget.php(52) : eval()’d code on line 1

It seems that the problem is not with Karma.

It is with this plugin “http://wordpress.org/extend/plugins/wp-php-widget/”.

It is trying to parse code from string, so please go back and see if you have written some PHP which occurs this error.
