A client has given me a Plesk account to install his PHP app in, but the PHP memory limit is only 32M and I'd like to increase it. I tried to find this setting on the admin panel but couldn't :(
There is no way to update it on the control panel.
What you need to do is to create a file called : vhost.conf
This file must be located in :
Inside this file, add (and change domain.com) :
<Directory /var/www/vhosts/domain.com/httpdocs/> php_value memory_limit 64M </Directory>
As root, run the following :
/usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=domain.com
Please note that if you use Fast-CGI this won't work, you would need to change it within the main php.ini.
EDIT: Added path to vhost.conf file
