I'm having this issue below.
Fatal error: Out of memory (allocated 301465600) (tried to allocate 32 bytes) in /home/romanzzino/public_html/lib/Zend/Db/Statement/Pdo.php on line 228
What could it be?
It's an issue related to the memory limit on your server or installation.
Improve these values on your .htaccess
and .user.ini
file, they're on your root installation folder and in your pub folder.
php_value memory_limit 512M
php_value max_execution_time 38000
If the solution above doesn't resolve, try to change the same limits on your php.ini
file on your server.
The memory is limited by the .htaccess
and the .user.ini
files used by Magento 2.
Increase the memory limit (e.g. up to 2048M) in the following places:
1..user.ini
memory_limit = 768M
2..htaccess (2 places)
php_value memory_limit 768M
3.pub/.user.ini
memory_limit = 768M
4.pub/.htaccess (2 places)
php_value memory_limit 768M
