PHP has a configurable memory limit to control memory allocation. Set too low and Koken may not function to its fullest potential. We recommend at least 64mb. You may check your server’s current PHP memory limit inside Koken by going to Settings > System.
Here are a couple of ways you may raise this memory limit yourself.
In Koken’s storage/configuration folder is a file named user_setup.php. Add the following line to it, and set the number to the value you want.
If editing user_setup.php doesn’t work, try adding the following to /koken/.htaccess:
php_value memory_limit 64M
Contact your web host
If neither of the above options work please contact your web hosting provider to request they raise it for you.
