If you are looking for IonCube Loader installation guide on Ubuntu (server) operating system, then this is the right place to find it. I’m sure you all ready came across many other out dated instruction online regarding this. If you follow any of those instruction, then your server/site will stop working because of server misconfiguration.
To make it even worse, the official documentation of ioncube loader is also providing out-dated instruction. After struggling one and half day, I finally figured it out.
If I’m not wrong you can follow this guide for other Linux based O.S. as well.
