i-MSCP >= 1.3.1 and PHP opcache - Unable to allocate shared memory segment

Dear community,

If during the update, you get the following error (When PHP-FPM is restarted):

This mean that you do not have sufficient memory available on your system. This generally occurs in virtualized environments (OpenVZ, LXC...) Indeed, the free -m output can lie... To fix the problem you must either disable opcache, or decrease the max memory assigned to it.

• If you want to disable opcache, edit the /etc/imscp/php/php.data file and set the PHP_OPCODE_CACHE_ENABLED parameter value to 0
• If you want to lower the memory, edit the /etc/imscp/php/php.data file and change the PHP_OPCODE_CACHE_MAX_MEMORY value

Once done, save the changes and run:

Then, restart the i-MSCP installer.

After editing /etc/imscp/php/php.data file which imscp command I have to call so the new settings take effect?
