Notice: Undefined variable: post_title

Still getting the same error about the undefined variable $post_title

Undefined variable: post_title in wp-content/plugins/ultimate-responsive-image-slider/layout.php on line 291

even though this ticket was marked as resolved and commenting was disabled:

The fix shown in the last bug report is still valid. Please simply copy & paste these two lines of code to fix this problem. Thanks.

One note:
The error only occurs when disabling ‘Display Slider Post Title’ in the slides options.
