 * Hi,
    I have the same issue as [https://wordpress.org/support/topic/warnings-in-error-log-2/](https://wordpress.org/support/topic/warnings-in-error-log-2/).
   And I var_dump `opcache_get_status()` as follow: ————
 *     ```
       array(5) {
             ["full_path"]=>
             ["hits"]=>
            ["memory_consumption"]=>
             ["last_used"]=>
            ["last_used_timestamp"]=>
           }
       ```
   
 * ——————
    Seems that my opcache_get_status() function does not provide `timestamp`,
   that’s the reason of occuring ‘PHP Warning: Undefined array key “timestamp”’.
   It’s not a critical issue and it does not affect the usage of the plugin. However,
   there are too many lines of such warning info in my debugging log, I want to 
   remove them. Thank you!

 * I suspect OPcache is misconfigured.
 * Could you run this script:
 *     ```
       <?php
       echo '<pre>' . var_export(opcache_get_configuration(), true) . '</pre>';
       echo '<pre>' . var_export(opcache_get_status(), true) . '</pre>';
       ```
   
 * And give me the FULL result please ?
