PHP Fatal error: Uncaught Error: Class 'vw_Hard_Core' not found

PHP Fatal error: Uncaught Error: Class 'vw_Hard_Core' not found

Hi there,

after changing the file mentioned in my previous bug report (https://www.vaultwiki.org/issues/5660/#note31036) I resumed the upgrade. It went on for a few seconds and then yielded a HTTP500 that the entire forum (not only ACP, but entire website) is stuck on.

PHP error log:

Code:

In src/addons/vw/vw/XF/Entity/UserProfile.php, find:

Code:

$structure = parent::getStructure($structure);

BEFORE it, add:

Code:

\vw\vw\Core::init();

Now the entire board loads, but looks like this (completely without css, I assume): https://gyazo.com/781958c4e0093fd82c5fda74fc34f464

Please check the content of the CSS that was loaded and XenForo's server error log. There might be errors in it which are preventing the CSS from loading.

I would recommend that you rebuild the add-on data, as it seems like your forum has class extensions in memory but not code event listeners. Add-Ons > Add-Ons > Installed Add-Ons > VaultWiki > [dropdown] > Rebuild.

If that doesn't work, you may have another add-on installed which uses code-event app_setup and returns false from its listener.

I cannot enter the AdminCP as it returns HTTP500 when logged in, too.

You will need to add the following to the end of your src/config.php file:

Code:

$config['enableListeners'] = false;

Once you perform the rebuild, you would remove this line to check whether it has worked.

Okay, initially I couldn't select "rebuild" as the upgrade was apparently still pending. So I re-ran the upgrade again with listeners disabled, then another error popped up:

Code:

In src/addons/vw/vw/Setup.php, find:

Code:

'where' => vw_DB::get()->query()->eq('hold', 1)

Replace with:

Code:

'where' => \vw_DB::get()->query()->eq('hold', 1)

In src/addons/vw/vw/_install/lib/upgradepath/steps/4/1/0/alpha/2/XF21/xf2.php, find:

Code:

$entity->option_value = $config;

Replace with:

Code:

$entity->option_value = [];

As for the original cause of this issue, I believe I've figured it out and it involves XenForo installing Class Extensions first and in a different request from Code Event Listeners. This is only a problem during VaultWiki upgrades when it expects to remain active throughout the process.

In src/addons/vw/vw/Setup/Caller/Upgrade.php, find:

Code:

$this->update_final();

BEFORE it, add:

Code:

$addon = $this->view->get('setup')->vwGetAddOn()->getInstalledAddOn(); if (!$addon->is_processing) { $addon->is_processing = true; $addon->save(); }

Alright, changed everything you told me and re-ran the upgrade with disabled listeners again and it went through this time. Then I enabled the listeners again. So far it seems to have worked.

Error 1: I have installed XenPorta 2 from Jaxel and the Home page (where the portal resides) now displays a generic error:
An error occurred while the page was being generated. Please try again later.

Nothing in PHP or XenForo error logs though

Error 2: I try to open the Wiki (navigation entry to domain.com/wiki/) and it tells me "The requested page could not be found."

Also neither PHP nor XenForo errors

I'll try to run the upgrade again with a fresh test copy of my production board as soon as the new version is out

Thanks and keep up the good work!

Edit:
Regarding error 2: I've now seen that it automatically redirects me to domain.com/wiki/ although I'm on test.domain.com. Changed the Wiki Base URL (and it's saying "in progress" since like 5 minutes after I saved) but it works now.
