Hi there - I had Q2W3 working great and reordered lots of posts. I left it alone for a couple of weeks and now when I try to sort more posts, when I click the Update Unsorted button, I get shown a 404 page with the URL mysite.com/wp-content/plugins/q2w3-post-order/post.php
The list doesn't update with the new sorting.
I have the same problem on 2 different sites. Could I please send you the debug script output, as I don't understand it but I can see the word "error" in there a few times.
I guess it must be user error on my part but I can't figure out what I would have changed to break the plugin like this.
