Root access to the Plesk server
The Plesk 12 micro-update #54 updates Roundcube to the latest 1.1.2 release. This requires a minimum of PHP 5.3.7 in order to function, whereas the default for CentOS 6 is fixed on the 5.3.3 release. If this is the case, you may see an error like the following:
You will need to install PHP >= 5.3.7 in order to use Roundcube webmail
The fix is to reconfigure Roundcube to use one of the alternative Plesk PHP versions, as detailed below.

- Ensure that you have multiple PHP versions installed via the Plesk components.
- Login as the root user to your server via SSH.
Update the roundcube.conf to use the PHP 5.5 interpreter as installed by Plesk. You can do this by running sed to do a search and replace:
sed s/fastcgi/plesk-php55-fastcgi/g -i.bak /etc/httpd/conf/plesk.conf.d/roundcube.conf
Restart Apache to apply the new config:
- Check that webmail now works as expected and that all other sites are working as normal.
