Hello there! We'd like to install the Suhosin Extension on a ispconfig 3 (3.0.4.6 / centos) server. For your knowledge, it will works out-of-the-box or we need to attend problem after that we will activate this extension? Thank you.
It should work out of the box and ispconfig does not conflict with suhosin. You can check with phpinfo() command if the installation worked and if suhosin is active.
