Re: Security Error: No _CSRFToken exists in session. Try reloading previous page
I sometimes encounter this issue when there's a mismatch between http and https URLs. Can you verify that the page(s) you're having issues with are using the correct protocol?
Yes, thanks, that was the issue. Sorry, that seems so simple :(!
Appreciate your help.
Glad that sorted it out! Simple solutions are always nice.
This can also happen if you are using the global /tmp directory for session storage which is the default.There may be system housekeeping tasks that remove the session storage files.
If possible change session.save_path in General Settings to the user account tmp directory. ~/tmp or may be hard coded using the home path instead of the tilde i.e. /home/useraccount/tmp. This will depend on the OS and control panel you are using. Easiest way to get the path is check Program Directory in General Settings. You might need to create the directory if it doesn't exist and make sure it is outside your web root.
