THE concern seems to be corrected with a version of Joomla >= 5.4 beta3 |
On a site hosted by OVH and if we activate the File cache I have this display error:
|
|
Warning: Zend OPcache API is restricted by "restrict_api" configuration directive |
If you look at the php options (displayed by phpinfo)
We have:
This means that there is a restriction of access to opcache by OVH
To fix this error I made a change in 
libraries\vendor\joomla\filesystem\src\File.php
I commented on the line that contains opcache_invalidate
/**
* Invalidate any opcache for a newly written file immediately, if opcache* functions exist and if this was a PHP file.
*
* @param string $file The path to the file just written to, to flush from opcache
*
* @return void
*/
public static function invalidateFileCache($file)
{
if (function_exists('opcache_invalidate')) {
$info = pathinfo($file);
if (isset($info['extension']) && $info['extension'] === 'php') {
// Force invalidation to be absolutely sure the opcache is cleared for this file.
//opcache_invalidate($file, true);
}
}
}
}
