Yii2: PHP Warning - Unable to allocate memory for pool

Yii2 error:

PHP Warning – yii\base\ErrorException

include(): Unable to allocate memory for pool.

* Reason : You have not allocated enough memory for APC cache (file cache or opcode cache)

* Solution 1: Disable APC, If you do not need it (apc.enabled=0)
* Solution 2: Increased memory for APC (apc.shm_size="64")

To do one of the two. Find php.ini or apc.ini on your server. If you do not have admin rights to the server try to use htacess file: php_flag display_errors on
