Issue I can only get OPcache to work with PHP7...

Richard18

Basic Pleskian
Am I doing something obviously wrong? The opcache extension handler is enabled for both PHP7 and PHP5 in 'PHP Settings' in Plesk.

In the 'additional directives' part of PHP settings for the subscription I've added:
Code:
zend_extension=opcache.so;
opcache.enable=1;
opcache.memory_consumption=64;
opcache.interned_strings_buffer=8;
opcache.max_accelerated_files=3000;
opcache.revalidate_freq=180;
opcache.fast_shutdown=0;
opcache.enable_cli=0;
opcache.revalidate_path=0;
opcache.validate_timestamps=2;
opcache.max_file_size=0;
opcache.file_cache=/var/www/vhosts/domain/.opcache;
opcache.file_cache_only=1;

If I switch the subscription to use PHP7 (7.0.12), the cache files are generated, if I delete the cache files and switch the subscription to run PHP 5 (5.6.27) no cache files are ever generated.

If I swap it back to PHP7, the cache files are generated.
