[E_NOTICE] Trying to access array offset on value of type null

Updated to XF 2.1.6 and now get an error and every wiki entry is showing as a stub

Could it be related to this note about XF 2.1.6 (https://xenforo.com/community/thread...anager.171879/)
P.S. I updated to 2.1.6a just in case it was solved that way, but the error is still happening.

This bug appears to be a showstopper, any ideas of what could be causing this?

In src/addons/vw/vw/_core/instance/renderer/xf2.php, find:

Code:

$item = $this->instance->get_item(); $node = vw_Hard_Core::model('Node')->one($item);

Replace with:

Code:

if ($this->item) { $node = vw_Hard_Core::model('Node')->one($this->item); } else { $node = vw_Hard_Core::model('Node')->one('Page'); }

This error is new due to changes in PHP 7.4, which there are no VaultWiki releases compatible with yet. This will be considered as part of PHP 7.4 compatibility handled in: https://www.vaultwiki.org/issues/5936/
