I'm going crazy trying to enable ioncube. My head won't go anymore. Here's my php -v output PHP 5.5.9-1ubuntu4.9 (cli) (built: Apr 17 2015 11:44:57) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with XCache v3.1.0, Copyright (c) 2005-2013, by mOo with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies with XCache Optimizer v3.1.0, Copyright (c) 2005-2013, by mOo with XCache Cacher v3.1.0, Copyright (c) 2005-2013, by mOo with XCache Coverager v3.1.0, Copyright (c) 2005-2013, by mOo I've tried adding zend_extension = /usr/lib/php5/20121212/ioncube_loader_lin_5.5.so to the very first line to every php.ini file (apache2, cgi, fpm and cli). Nothing works. Adding the line only to the apache php.ini file will throw error that apache didn't start within 20 seconds and in the logs I keep finding that the loader should have been loaded first (I did, the very first line of the ini file). Adding the line only to the cgi php.ini file will throw 500 error for ISPconfig. Apache will work fine, but no ioncube of course. Obviously the library is where it should be. I've searched and searched and all I can find is different problems or incomplete solutions.
