Manager does not recongnize opcache running

OPcache is not fully operational or in restricted mode.

OK, howto recognize restrited mode in opcache?
here is my php.ini

; Memcached by OPCache
zend_extension = opcache.so
opcache.enable = 1
opcache.file_cache = /kunden/homepages/20/d34869179/htdocs/.opcache
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

Wich settings to php.ini i have to change, to let your plugin working? …to set your plugin able to recognize opcache is installed and working?

May I ask you what’s your PHP version and who is your hoster?

The problem was found.
php.ini (opcache enabling) must be stored also in wp-admin – folder

Great!
