Zend Opcache is enabled by php.ini, but uses an unsafe configuration

Hello all,
I have just bought this and installed it fine but when I go to the VaultWiki installer page via the ACP in Xenforo, I get this error;

Failed to Meet Minimum Requirements

Zend Opcache is enabled by php.ini, but uses an unsafe configuration. PHP files can still read from the cache during upgrades. This behavior can result in unintended database damage.

I have no idea what this means and hope you can assist...
I was hoping it would work out of the box, but obviously it doesn't like my setup.

Many thanks

This was fixed November 1; maybe the fix didn't work in XenForo. If it works correctly, it should tell also you which of the following settings is wrong and how to fix them:

opcache.validate_timestamps should not be 0
opcache.revalidate_freq should not be higher than 10

This issue was only affecting XenForo beyond November 1. Since 2013, the subclass which checks for specific XenForo requirements had changed the name of the variable where the requirement value was stored. This made it impossible to show the correct values for any requirements that failed under XenForo, for which a specific minimum value could be specified.

This is now fixed in build 002.

I'm also having this issue.

opcache.revalidate_freq is too high (120). Please lower this value to at most 10 and restart PHP.

My host can't really change it because of the larger sites that require it.

With a value of 120, It will take 2 minutes for PHP to notice changes to the file system. This means you have to wait at least 2 minutes after uploading an upgrade package before you attempt to access the wiki or execute the upgrade routines. Failure to do so will probably damage the database. Many users have damaged their database by doing this, and that is why this warning was added. If you do not have control over these ini settings, then you will need to submit a Ticket Support service, under our Members tab > Services > Free Services, and we will temporarily disable this protection.

If you have PHP > 5.5, you can make this edit which should bypass the error. In vault/core/controller/cp/install/vw.php, find:

Code:

if ($revalidate_freq !== false AND $revalidate_freq > 10)

Replace with:

Code:

if ($revalidate_freq !== false AND $revalidate_freq > 10 AND !opcache_reset())
