      Non-admins experiencing intermittent blank pages on new posts, replies
      Users (and admins) are occasionally receiving blank pages after adding replies and posting new threads.
      Users (and admins) are occasionally receiving blank pages after adding replies and posting new threads. I'm using vB 3.7.3 and VaultWiki 2.1.3.

      This has happened with Quick Replies, unquoted replies, and quoted replies.

      Same here when posting a reply to a article. Error-message on the white-page: The requested URL /s&do=comments&p=86 was not found on this server.
      But the replies are saved and in reality there.

      I get no error messages at all—just a blank, white screen. View source shows that no html is there at all.

      The messages do save. If I refresh the page at the white screen, I get the "duplicate message" error.

      I can vaguely see why this might happen in a wiki thread. If this only occurs when replying to wiki threads, then the following should fix it. Modify the plugin called "New Article - Cache Article" at the hook location newpost_complete.

      Replace all the code with:
      PHP Code:
      global $vault;

      if (
                $vault->misc['creating_article'] OR
          (
                    $type == 'reply' AND
                    $foruminfo['vault_type'] > 0
                )
      )
      {
                $userfield = '';

          if (      $vault->misc['creating_article'])
          {
                    $userfield = 'post';
          }
          else
          {
                    $post['threadid'] = $dataman->fetch_field('threadid');
          }

                $post['userid'] = $dataman->fetch_field($userfield . 'userid');
                special_newpost_complete($post, $type);
      }

      if (      $type == 'reply' AND empty($GLOBALS['threadinfo']['threadid']))
      {
                // we corrupted threadinfo, and this is a real shitty way to fix it
                $GLOBALS['threadinfo'] = fetch_threadinfo($dataman->fetch_field('threadid'), false);
      }

      pegasus,

      It occurs when replying to normal threads, oddly enough.

      pegasus,

      I watched the headers with Tamper Data when posting replies. When it works, I get a 302. When it doesn't, I get a 200.

      Which hooks do you use? Is there a way to log them?

      ETA: Nevermind, I found the hooks.

      I added the new plugin code and am still having issues.

      Thanks,

      Rand

      This requires further testing on my part. I am looking into this, but so far I have been completely unable to reproduce it.

      Forgot to remove a $ in the above replacement code. Try using the new code, and this problem should go away. Product file in ZIP has been updated to reflect these changes.

      pegasus,

      I eliminated the problem by disabling all plugin hooks, but that is no good. Is the replacement code in your 12/12 post up-to-date? I'd like to try this again. (If this fails, I will try re-enabling each hook one-by-one to track down the problem.)

      Apologies for the delayed response. The holidays were long.

      The 12/12 code should work.
