I have the same Issue, have worked with my ISP 1and1.com AND THE IONCUBE IS INSTALLED and RUNNING????
I run the IonCube Test and it responds with:
ionCube Loader Wizard
Loader Installed Successfully
The ionCube Loader version 4.7.3 for PHP 5.4 is installed and encoded files should run successfully.
But the Site still gives me this error when trying to login with the admin_login:
Site error: the file /homepages/17/d555836963/htdocs/index.php requires the ionCube PHP Loader ioncube_loader_lin_5.4.so to be installed by the website operator. If you are the website operator please use the ionCube Loader Wizard to assist with installation.
I wish someone at JROX would answer my support ticket on this same issue and provide some help to resolve it!
