Plugin “Move WordPress Comment” not working anymore

I just noticed that this really great plugin “Move WordPress Comment” was failing when trying to move comments. Fortunately, the fix was easy.

This plugin is very useful when you started a discussion thread (I.e.: you reply on a comment), but the person does not answer on the last comment. Instead, he starts a new comment. In such a case, the plugin can be used to move his last comment under the last reply in the discussion thread;

Example, here under, I could attach the second discussion thread under the last reply of the first discussion thread by typing the id #46705 of that last reply into the “parent comment” of the first comment #46719 of the second discussion thread and clicking “Move”.

Unfortunately, this plugin is now returning an error “Uncaught ArgumentCountError: Too few arguments to function wpdb::prepare()”

The fix is really simple. Go to your WordPress Dashboard, under the menu “Plugins” and select the “Plugin Editor”.

Next, in the top-right corner, set “select plugin to edit” = “Move WordPress Comment” and click “Select”.

Then, go to line 63 or search for “prepare”. This methods requires 2 parameters. So, in the where clauses of the SQL Update statements, replace the variables by %s and move the variables into a second parameters.

It should result into this:

// move to different post
if ( $postID != $oldpostID ) {
$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->comments SET comment_post_ID=$postID WHERE comment_ID=%s;", "$commentID") );

// Change post count
$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET comment_count=comment_count+1 WHERE ID=%s", "$postID" ) );
$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET comment_count=comment_count-1 WHERE ID=%s", "$oldpostID" ) );

// move to different parent
if ( $parentID != $commentID ) {
$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->comments SET comment_parent=$parentID WHERE comment_ID=%s;", "$commentID" ) );

Finally, click on “Update File”, at the bottom of the Plugin Editor.

Et voilà,
