      1) This occurs in PHP 7.4 if no areas have been modified in the Area Manager since the last time an area was deleted, due to the area cache not being rebuilt after areas being deleted. This is fixed in the next build by causing area deletes to rebuild the cache, but we also account for damaged caches and race conditions with the following change. In src/addons/vw/vw/_core/view/factory/area/vw.php, find:
      Code:
      if (!$area['displayorder'] OR !vw_Hard_Core::model('UI')->check('can_main_tab', $area))
      Replace with:
      Code:
      if (!$area OR !$area['displayorder'] OR !vw_Hard_Core::model('UI')->check('can_main_tab', $area))
      2) This occurs in PHP 7.4 when attempting to view the comments tab for a page that has no comments yet. In src/addons/vw/vw/_core/controller/ui/discussion/vw.php, find:
      Code:
      $discussionid = $itemcheck['discussionid'];
      Replace with:
      Code:
      if ($itemcheck) $discussionid = $itemcheck['discussionid'];
      3) This occurs when the last-update field for a discussion is not empty but contains a corrupt value. Since it is not clear why your value is corrupt, I don't recommend fixing the error at this time. Instead, attempt to fix the affected last-update field by adding a new comment to that discussion.

      For your code replacement in number 2, the file (at least as I have it installed in 4.1.0 RC1 Build 2) does not have that code string.

      Finally found the string -- for some reason the search function didn't want to work, so I had to find it manually.

      Will follow up and let you know if further errors are returned.

      For Error #3 above, I was able to reproduce it myself, after having another error come in this morning identical to it.

      It happens when I try to post a discussion reply to the Wiki entry. The Wiki is showing six (6) pages of discussion posts, but will ONLY display the first of the six pages. When I try to page to the second...third....sixth pages, it shoots me out of the thread to the main Wiki category area.

      I was able to post a comment to the Wiki entry (from the form at the bottom of the first page of discussion posts), but am not actually able to view what I posted. My main home screen does indicate that a post was made by me, so it is updated.

      Doing this threw the following two errors:

      ERROR #1

      Thanks for the new information. I was finally able to reproduce it on my test board.

      #3 occurs when you create a new discussion and post the first comment at the same time. In this case, any place that tries to show that discussion in a list will throw this error when rendering the last-update info for that discussion. This is due to the content being created at the same time as its last-update, which is a special case where we want to use creation-info instead of last-update, so we have a problem where we are trying to skip something that we are already rendering.

      In src/addons/vw/vw/_core/view/factory/last/vw.php, find:
      Code:
      if (!empty($lastupdate['iteminfo']))
      Replace with:
      Code:
      if ($lasttypeid AND !empty($lastupdate['iteminfo']))
      For that final error, edit src/addons/vw/vw/_core/model/cron/deferred/digest/vw.php, find:
      Code:
      		else if (
			// we are subscribed to a page
			$pagetypeid == $subscription['nodetypeid'] AND
			// the content is directly beneath the page

			$subscription['nodeid'] == $item['pageid'] AND
			// if the content is a comment, it's in the main discussion
			($itemtypeid != $commenttypeid OR empty($item['talktype']))
		)
		{
			return 'item';
		}
      Replace with:
      Code:
      		else if (
			// the content is a comment in the main discussion
			$itemtypeid == $commenttypeid AND
			empty($item['talktype']) AND
			(
				// we are subscribed to that content
				(
					isset($item['contentid']) AND
					$item['contentid'] == $subscription['nodeid'] AND
					$item['contenttypeid'] == $subscription['nodetypeid']
				) OR
				// we are subscribed to that page
				(
					$pagetypeid == $subscription['nodetypeid'] AND
					isset($item['pageid']) AND
					$subscription['nodeid'] == $item['pageid']
				)
			)
		)
		{
			return 'item';
		}
		else if (
			// we are subscribed to a page
			$pagetypeid == $subscription['nodetypeid'] AND
			isset($item['pageid']) AND
			$subscription['nodeid'] == $item['pageid'] AND
			$itemtypeid != $commenttypeid
		)
		{
			return 'item';
		}

      Things seem to have been resolved since updating the code last night.

      One issue remains, though -- I am not able to page through the comments on the Wiki thread. I can see the first page, but there are a total of six pages of comments, and I can't scroll to successive pages. When I do (click on a number or next), it still kicks me out to the main Wiki area page.

      It looks like this occurs if the main discussion of a wiki page is set to display underneath the page, instead of a separate tab. In this case, the page-nav for the main discussion has invalid links, due to XF 2.x not knowing how to handle links with hashes (the hash to jump to the comments).

      In src/addons/vw/vw/XF/Mvc/Router.php, find:
      Code:
      return parent::buildLink($link, $data, $parameters);
      Replace with:
      Code:
      		$hash = false;

		if (!is_array($link))
		{
			$hashly = explode('#', $link, 2);

			if (isset($hashly[1]))
			{
				$link = $hashly[0];
				$hash = $hashly[1];
			}
		}

		$built = parent::buildLink($link, $data, $parameters);

		if ($hash)
		{
			$built .= '#' . $hash;
		}

		return $built;

      That last fix solved the issue, and now all pages of discussion posts can be viewed. Thanks much.
