IMPORTANT: For version 2.3+ Increasing memory allocated to PHP

First alternative:

Edit php.ini and increase memory_limit.

memory_limit = 128M;       Maximum amount of memory a script may consume (8MB)

Second alternative:

Edit config.php and add new memory_limit:

ini_set('memory_limit', '128M');

ERROR: Warning: strtotime() & date()

IMPORTANT: From version 2.3+, you can set the default timezone in the oc-admin settings.

You need to specify the default timezone.

Edit config.php and add:

date_default_timezone_set('Asia/Kuala_Lumpur'); // change Asia/Kuala_Lumpur for your timezone

php.net date_default_timezone_set
