[4.1 Alpha 3] XF1.5 installation exception (preg_match_all() expects parameter 2 to be string, array given)

After reading your earlier post that recommends upgrading VaultWiki to 4.1 on XenForo 1.5 before upgrading XenForo to 2.0/2.1, I have set up a new private instance of XF1.5 for testing purposes.

I am unable to finish installing VaultWiki 4.1.0 Alpha 3 to a new copy of XenForo 1.5.21, as the install script is interrupted by an error exception at 38% (Step 10):

The last section of installation log:
Step 8
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special(3)
Preparing database
Updating data in table: vw_block
Step 9
Adding data to table: vw_page
Creating required and example areas
Step 10
An exception occurred: preg_match_all() expects parameter 2 to be string, array given in [vw-core]/view/global/xf.php on line 77

In library/vw/_core/instance/progress/xf0.php, find:

Code:

vw_Hard_Core::view('Global')->replace_phrases($content, 'html');

Replace with:

Code:

		if (is_array($content))
		{
			foreach ($content AS $key => $text)
			{
				$content["$key"] = $this->preformat($text);
			}
		}
		else
		{
			vw_Hard_Core::view('Global')->replace_phrases($content, 'html');
		}

Thanks. Installation resumed and the "Moderator Settings" overlay has two radio options, without any label:

Code:

<dl class="ctrlUnit">
  <dt>Moderator Group</dt>
  <dd><ul class="vw-progress-input-radio">
    <li id="yui_3_5_0_1_1554125118954_45" style="display: flex;">
        <input type="radio" name="vw_moderator_type" value="0">
      </li>
      <li id="yui_3_5_0_1_1554125118954_48" style="display: flex;">
        <input type="radio" name="vw_moderator_type" value="1">
      </li>
    </ul>
    <p class="explain hint">Choose the user group that will be used for wiki moderators.</p>
  </dd>
</dl>

It doesn't matter which label-less option I choose at Step 10, as both result in:
<span style="color: #f00">The selected user group is not usable for this purpose.</span>
(the html elements are part of the error message)

Fixed in the next build. In js/vw/vw/cp-progress.js, find:

Code:

li.appendChild(this.dialog_row(radio, tag));

Replace with:

Code:

li.appendChild(this.dialog_row(radio.label, tag));

Thanks, this fixed the UI side of things for Step 10. I was still unable to proceed with the Create new usergroup option (error: The selected user group is not usable for this purpose.). However, I was able to choose an existing user group and then the installation script continued to 99%.

At 99% (Step 25), the installation stalls with a console message logged:
POST /admin.php?wiki/upgrade&progress=1 500 (Internal Server Error)

However manually refreshing the page reveals that the installation seems complete, i.e. the usual menus appear and I can access various settings without an issue (e.g. Area Manager, Prefix Manager, Discussion Topics, etc..). Navigating to "Run Upgrade Script" brings up the installer at 99%.

Details about that 500 Internal Server Error:
