Hi there!

Please enable debugging by adding $Configuration['Debug'] = TRUE; to your /conf/config.php file. Once that is done, visit the blank page and report back with the new error.

Thanx for the comment.. this is the error

Fatal error: Invalid opcode 153/1/8. in *******/plugins/QnA/class.qna.plugin.php on line 415

your problem may be with eaccelerator and anonymous functions.

in any event whatever the matter - you need to change the anonymous function.

around line 415

try changing this  -   I haven't test it though.

$Comments = array_filter($Comments, function($Row) {
            return strcasecmp(GetValue('QnA', $Row), 'accepted');
         });


to this:


        $AcceptRow = strcasecmp(GetValue('QnA', $Row), 'accepted');
       $Comments = array_filter($Comments, $AcceptRow);

DON'T do the change above you could this.

instead around line 410

your code would look like this with CHANGES.

what it will do is allow you to run the QNA because anonymous functions won't work in your setup
so the code below comments out all the comment filtering.

and it displays the best answers at the top,

and it shows ALL the answers (rejected and accepted, etc) in chronological sequence.

To me this is the best of both worlds.

• Best answers at top and
• all answers in chronological order,
• there is some duplication of answers but it is easier to see the answer process with all answers in chronological order.

This is my LAST attempt at messing with the QNA, but I wanted to get you out of a jam that I caused for you in the previous untested attempt above.

If this solution is not satisfactory, you can seek help from others (not me).

      $Sender->SetData('Answers', $Answers);
/*
      // Remove the accepted answers from the comments.
      if (isset($Sender->Data['Comments'])) {
         $Comments = $Sender->Data['Comments']->Result();
         $Comments = array_filter($Comments, function($Row) {
            return strcasecmp(GetValue('QnA', $Row), 'accepted');
         });
         $Sender->Data['Comments'] = new Gdn_DataSet(array_values($Comments));
      }
 */
  }

   /**
    * Write the accept/reject buttons.
    * @staticvar null $DiscussionModel
    * @staticvar boolean $InformMessage
    * @param type $Sender
    * @param type $Args
    * @return type
    */
   public function DiscussionController_AfterCommentBody_Handler($Sender, $Args) {

cut and paste carefully and make sure your brackets are correct.

I did test these changes and it works for me.

follow the instructions in

around line 415 or so. /plugins/QnA/class.qna.plugin.php

you need to comment out entire routine either use /* */ to comment entire block or

// if (isset($Sender->Data['Comments'])) {
//$Comments = $Sender->Data['Comments']->Result();
//$Comments = array_filter($Comments, function($Row) {
//return strcasecmp(GetValue('QnA', $Row), 'accepted');
//});
//$Sender->Data['Comments'] = new Gdn_DataSet(array_values($Comments));
// }
