Hello all of you out there frustrated with the Zero response to the issues with the Sidebar Generator. I had a word press site that used this plugin and after upgrading it no longer worked or appeared to.
After playing with the plugin and testing it after the 3.1 upgrade is related to the saving the post. It turns out that the database table wp_postmeta was getting populated with a JSON string of php output
SELECT * FROM `wp_postmeta` where meta_value like '%<?=$i?>%'
Just replace the lines with this one
<select name="sidebar_generator_replacement[<?php echo $i; ?>]">
