I followed the perfect server guide for Debian 8 Jessie. Then wanted to install IONCUBE and followed the guide below: https://www.howtoforge.com/install-...p-modes-cli-cgi-fcgi-and-fpm-on-debian-wheezy using: Code: zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.6.so Apache would not take it, I kept getting "zend_mm_heap corrupted" in the error logs and nothing that required it seemed to work. The only thing that fixed it was the old version of it I had on the old server I was migrating from. I copied the older versions and it all began to work.
