Mine is also in a sub dir. could it be happening only if WP is installed in a sub-dir ? * Plugin seems to work OK … just get this warning !?! * Best Chris * Thread Starter [dimal](https://wordpress.org/support/users/dimalifragis/) * (@dimalifragis) * [5 years, 11 months ago](https://wordpress.org/support/topic/array_unshift-expects-parameter-1-to-be-array-null-given/#post-13030809) * [@chrisbz](https://wordpress.org/support/users/chrisbz/) * Thanks for the report, so i don’t feel alone 🙂 * My WP is not in a subdirectory.
