Since the constructor for Setup.php loads the vw_Hard_Core class...

Code:

if (!class_exists('vw_Hard_Core', false)) { Core::init(); }

It looks like this can only happen if neither of the following files are readable (you must have at least one):
src/addons/vw/vw/config.php or src/addons/vw/vw/config.php.xf2
If these files are "missing" then Core::init() would fail and the class would not be loaded.

This can happen if you just uploaded the ZIP for the first time and the files are not done uploading yet, or
This can happen if you have removed or renamed the files to something else, or
This can also happen if the "realpath" to the file returns a failure. For one, this may happen if one or more directories in the path name do not have the executable bit for the system user that PHP is running as.

If the files were not done uploading yet or one of the files was misnamed and you've fixed it, all you need to do is restart the PHP server process (clears the PHP opcache which may have cached that the file was not found), and retry clicking the Install button.

If the issue is due to permissions and you are unable to set the permissions as described, please try the following change. In src/addons/vw/vw/Core.php, find:

Code:

$path = \XF::getSourceDirectory() . '/addons/vw/vw'; $path = realpath($path);

Replace with:

Code:

$ds = DIRECTORY_SEPARATOR; $path = \XF::getAddonDirectory() . $ds . 'vw' . $ds . 'vw'; $rpath = realpath($path); if ($rpath) { $path = $rpath; }

Interestingly I have neither of those config files present under vw/vw

They exist in the zip file I downloaded. is it enough to just copy the vw/vw folder to my site?

the confix.php.xf2 and icon.png seem not to have been copied during the initial install for some reason.

The permissions are otherwise correct.

Yes, if you are missing files, just upload them and try again.

OK, I uploaded the missing files and got further, but now I am getting:

Based on this error and the previous error, and that the MySQL definition files in the copy of the ZIP you received contain the column definition for 'page_settings', you may somehow be installing VaultWiki on top of a previous VaultWiki installation (before 4.1.8) that was not removed first. Not sure how XenForo allowed that, but here we are.

Based on our records, the last version you may have installed was 4.1.7. In that case, we need to manually apply database changes to the tables you already had. In src/addons/vw/vw/_install/db/insert/vw.php, find:

Code:

foreach ($dms AS $datatype => $data)

AFTER it, add:

Code:

if ($datatype == 'index') {
			$dbalter = vw_Hard_Core::controller('DBalter')->get();

			if ($dbalter->fetch('vw_feed'))
			{
				$dbalter->add_field(array(
					'name' => 'feed_settings',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));

				$dbalter->add_field(array(
					'name' => 'feed_protect',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_book'))
			{
				$dbalter->add_field(array(
					'name' => 'book_options',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));

				$dbalter->add_field(array(
					'name' => 'book_protect',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_category'))
			{
				$dbalter->add_field(array(
					'name' => 'category_options',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));

				$dbalter->add_field(array(
					'name' => 'category_protect',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_disambiguation'))
			{
				$dbalter->add_field(array(
					'name' => 'disambig_options',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));

				$dbalter->add_field(array(
					'name' => 'disambiguation_protect',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_page'))
			{
				$dbalter->add_field(array(
					'name' => 'page_settings',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_team'))
			{
				$dbalter->add_field(array(
					'name' => 'team_options',
					'type' => 'int',
					'attributes' => 'UNSIGNED'
				));

				$dbalter->add_field(array(
					'name' => 'team_protect',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED'
				));
			}

			if ($dbalter->fetch('vw_special'))
			{
				$dbalter->add_field(array(
					'name' => 'fieldcache',
					'type' => 'blob'
				));
			}
}

If you are able to successfully complete the installation from this state, you may want to:

Installation completed.
"Uninstall" VaultWiki from the addon manager.
"Install" VaultWiki from the addon manager.

This should ensure that you are starting with a clean database and don't have to contend with data from a previous installation that may result in undefined behavior... or at least it might reveal why you had a partial existing installation to begin with.

baby steps it seems.

Got much further but now get: Exception: MySQL statement prepare error [1054]: Unknown column 'featured' in 'field list'

I don't get the full call stack, only an error Add-on batch result
One or more of the add-ons in this batch failed to install/upgrade. Click or hover over the error icon to view details of the error.

Based on the message, I would be surprised if you progressed much. It seems you are indeed missing all the new columns added in 4.1.8, suggesting an existing 4.1.7 installation. Assuming a similar call stack, now replace the previous code change with:

Code:

if ($datatype == 'index') {
			$dbalter = vw_Hard_Core::controller('DBalter')->get();

			if ($dbalter->fetch('vw_discussion'))
			{
				$dbalter->add_field(array(
					'name' => 'featured',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED',
					'length' => 1
				));
			}

			if ($dbalter->fetch('vw_feed'))
			{
				$dbalter->add_field(array(
					'name' => 'featured',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED',
					'length' => 1
				));
			}

			if ($dbalter->fetch('vw_feeditem'))
			{
				$dbalter->add_field(array(
					'name' => 'featured',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED',
					'length' => 1
				));
			}

			if ($dbalter->fetch('vw_page'))
			{
				$dbalter->add_field(array(
					'name' => 'featured',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED',
					'length' => 1
				));
			}

			if ($dbalter->fetch('vw_special'))
			{
				$dbalter->add_field(array(
					'name' => 'featured',
					'type' => 'tinyint',
					'attributes' => 'UNSIGNED',
					'length' => 1
				));
			}

			if ($dbalter->fetch('vw_comment'))
			{
				$dbalter->add_field(array(
					'name' => 'embed_metadata',
					'type' => 'blob',
					'null' => true
				));
			}

			if ($dbalter->fetch('vw_feed'))
			{
				$dbalter->add_field(array(
					'name' => 'embed_metadata',
					'type' => 'blob',
					'null' => true
				));
			}

			if ($dbalter->fetch('vw_redirect'))
			{
				$dbalter->add_field(array(
					'name' => 'embed_metadata',
					'type' => 'blob',
					'null' => true
				));
			}

			if ($dbalter->fetch('vw_revision'))
			{
				$dbalter->add_field(array(
					'name' => 'embed_metadata',
					'type' => 'blob',
					'null' => true
				));
			}

			if ($dbalter->fetch('vw_special'))
			{
				$dbalter->add_field(array(
					'name' => 'embed_metadata',
					'type' => 'blob',
					'null' => true
				));
			}
}

If this has no effect, I'll need you to find the new call stack in XenForo's Server Error Logs.

OK, something very strange is going on. When I made that change I went back to the install and dicovered that it thought it was installing 4.1.7 again. So I uninstalled vw and deleted vw from the addon folder. I then uploaded 4.1.9 again and installed it and got the missing vw_Hard_Core class. Went back to the add on page and it was showing an install of 1.4.7. SO I think something must be leftover in the previous install.

If you submit a ticket I can figure out what is happening and clean out the old installation manually:

Your installation has been repaired, and VaultWiki 4.1.9 is now installed successfully.

First, it appears that XenForo's batch add-on installer will not upload any file from the ZIP that does not appear in the hashes.json file. For VaultWiki, the config file and various binary files, such as image files, are not listed in hashes.json. This explains why the config.php.xf2 file was missing. We've updated our download system so that the hashes for these files are added to future downloads. For now, you may need to manually upload some files, such as files in the styles/vw/vw folder, in order to see any missing images.

Second, as theorized earlier, a previous installation of 4.1.7 was preventing installation of 4.1.9, but XenForo had placed it in an inconsistent state. This means you were not allowed to upgrade the add-on, or uninstall it, even though there was data in the database. Your logs showed that 4.1.7 was successfully installed in April 2024, so the inconsistent state was confusing. Unfortunately, the state is overwritten every time you attempt to install, so it's very difficult to tell what happened in the first place. Most likely you had a partial reinstall attempt in 2024 and forgot about it until now, then basically continued 4.1.7 install progress using 4.1.9 files.

Since the initial report of the missing class has been resolved with updated hashes (which are provided by our web site and not tied to any precompiled file), and since the installation was successful and encountered no errors once started from a cleaned database, this issue is being marked as VW.org Bug.

Thank you very much Ted. No idea how we got in that state. We started to look at migrating from XenCarta to VaultWiki some time ago then other priorities got in the way (as they often do). We are now starting that project up again and wanted to upgrade to the latest version and then this issue.

We very much appreciate your fast and full support on this.
