    This may be due to server restrictions in place.
    The necessary zend_extension line could not be found in the configuration.
Please also note the following:
The correct loader for your system has been found at /home/admin/web/websiteguardtest.tk/public_html/ioncube/ioncube_loader_lin_5.6.so. You may wish to copy the loader from /home/admin/web/websiteguardtest.tk/public_html/ioncube/ioncube_loader_lin_5.6.so to /usr/lib64/php/modules

i disabled open_base dir in the template files associated as i thought this could be the issue but its not, i am not sure what the issue is with ioncube and my vestacp machine any help would be apprecaited.
