[Escalated to 2nd Tier] We can see some alerts related to string translation in the error logs

Hi there,

it looks like Zend OPcache is not allowed to be used on the current hosting environment.

WPML String Translation is trying to interact with OPcache (to create or cache a PHP file), but your PHP configuration has this directive enabled:

opcache.restrict_api

When this is set, only scripts in a specific directory are allowed to call OPcache functions. Your plugin file:

/wp-content/plugins/wpml-string-translation/.../CreatePhpFileCommand.php

is outside that allowed path, so PHP throws the warning.

Also, I noticed that the WP Memory Limit is at 40M, if possible, please increase it to 256M or higher.

-------------

Are you currently hosting the site on wordpress.com by any chance?

This is important, because wordpress.com is strict and most likely won't allow you to edit the php.ini

--------------

If you are not you will most likely be able to edit your php.ini

1. edit your php.ini and either remove or comment out:

opcache.restrict_api=

Or set it to empty:

opcache.restrict_api=""

Then restart PHP / your web server.

If you are on wordpress.com or another hosting environment where editing php.ini is not possible, then you can supress the warnings by deactivating debug, debug display and debug log.

add the following to your wp-config.php

define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);
define('WP_DEBUG_LOG', false);
@ini_set('display_errors', 0);

NOTE: Always have a working backup before making any changes to your database or code.

Thank you for sharing the feedback from the WP team.

I have escalated this issue to our second tier and will update you as soon as I have feedback.

In the meantime you can use the recommendation of turning off debug display and logging which will prevent it from showing in the front end or filling up your log as a temporary workaround.

The warning will not affect the way WPML or your site work as it's not a FATAL error.
