Hi Daniel,
The snippet is [phpinclude file='/opt/bitnami/apache2/htdocs/abc/index.php']
which is a simple plugin that includes the file. It is triggered in the body of the page.
And index.php contains the line:
if (!isset($_SESSION)) session_start();
I’m afraid that I can’t try to replicate that outside of Bitnami as I haven’t set up a non Bitnami server. Do you think it’s linked to the environment? Bitnami is a very simple LAMP setup though. I find it surprising.
Thanks for the plugin, and the support!
