You are getting a blank page when enabling the JTurbo plugin because there is a PHP fatal error occurring on the backend. Can you please enable the JTurbo plugin and then go to the page that is showing up blank and append a ?debug=1 url variable to web address location.
For example if the location of the page that is showing up blank is:
www.<your-domain>.com/index.php?option=com_somethingthen please change it to:
www.<your-domain>.com/index.php?op...omething&debug=1or if the location is:
www.<your-domain>.com/index.phpthen change it to:
www.<your-domain>.com/index.php?debug=1This will cause JTurbo to output the PHP fatal error that is occurring on the backend. Once you receive the error, please post it here so I can tell you what the issue is. Then you can disable the JTurbo plugin again so that your website continues to function normally while we troubleshoot.
Thank you,
John
