What happens when you disable the font optimize feature (while the plugin is active), do the warnings stop? * Thread Starter [mookie4a4](https://wordpress.org/support/users/mookie4a4/) * (@mookie4a4) * [4 years, 8 months ago](https://wordpress.org/support/topic/php-warning-306/#post-14835162) * I have disabled the font optimize setting and the warnings have stopped. * Cheers * Plugin Author [Optimocha](https://wordpress.org/support/users/optimocha/) * (@optimocha) * [4 years, 8 months ago](https://wordpress.org/support/topic/php-warning-306/#post-14835185) * [@mookie4a4](https://wordpress.org/support/users/mookie4a4/) awesome (that we’re making progress). In that file that’s throwing the warnings, can you replace line 11: * `private $families;` * With the following: * `private $families = [];` * And enable the font optimize feature again, see what happens? * Thread Starter [mookie4a4](https://wordpress.org/support/users/mookie4a4/) * (@mookie4a4) * [4 years, 8 months ago](https://wordpress.org/support/topic/php-warning-306/#post-14835298) * Yep that seemed to have fixed it, no more warnings with the setting back on. * Plugin Author [Optimocha](https://wordpress.org/support/users/optimocha/) * (@optimocha) * [4 years, 8 months ago](https://wordpress.org/support/topic/php-warning-306/#post-14835325) * [@mookie4a4](https://wordpress.org/support/users/mookie4a4/) awesome!
