That error means that your code was generated with a version of ionCube for PHP 5.3. That means that your software is ancient. You can only run this software on PHP 5.3 (or maybe earlier). But the oldest version of PHP we offer right now is PHP 5.4.
That said, PHP 5.4 was released in 2012. If your software doesn’t support PHP 5.4, that software probably hasn’t been updated since at least that long.
So you could try to find a host which can run such ancient software, but I would recommend to consider migrating to newer, actively supported software which can run on modern PHP versions.
