We did recently change from php5.6 to 7.0, actually it's set as 7.0 overall but using htaccess to set some software to 5.6 for now until updated (Xenforo test site is running php7). I tried rebuilding from add-on options first, then tried a complete uninstall/re-install, any ideas? If this needs to run php5.6 or similar let me know so we can switch but would prefer to use php7 for security and other reasons.

If you are receiving this error then your environment might actually be using PHP 5.6 or a 7 Beta/RC, as the second parameter was added in 7.0.0: http://php.net/manual/en/function.unserialize.php

Fixed in the next build by checking the PHP version and omitting the second argument if that version is lower than 7.0.0.

In src/addons/vw/vw/_core/controller/fetch/vw.php, find:

Code:

return unserialize($result, array('allowed_classes' => false));

Replace with:

Code:

static $php7; if ($php7 === null) { $php7 = (version_compare(PHP_VERSION, '7.0.0') >= 0); } if ($php7) { return unserialize($result, array('allowed_classes' => false)); } return unserialize($result);

Ahh I see, makes sense and with the file change install is proceeding normally.

Side Note: When will the importer be done for the new Xenforo version? You can pm if you wish, thanks for the help .
