Undefined index

Hi Steve!

Please check if you set at least one post type in “Post types used by WRI” checkbox group on General settings tab of the plugin.
I think the main reason of the problem can be that there is not any post type selected there.
I suppose if “Post types used by WRI” checkbox are set, this problem does not occur.

However this setting causes a problem in the plugin, what we will fix in the following version. It can be done manually by changing 406 line of wri.php:

original line:
if ( is_array( $wri_general_settings['wri_used_posttypes'] ) ) {

new, fixed line:
if ( isset( $wri_general_settings['wri_used_posttypes'] ) && is_array( $wri_general_settings['wri_used_posttypes'] ) ) {

You can do this modification since the next release issued.

Cheers,
Peter
