Quote:To the best of my knowledge there isn't any error message with the exact text "Invalid CSRF token" in the CI core. So that kind of points to some custom code.
Your absolutely correct, I had integrated an off the shelf login system at the start of the project - after a lot of troubleshooting your comment pointed me in the right direction and it was this login system I was autoloading in via a custom library that was causing the conflict.
When I installed it I tested it but it didn't present an issue until now.
Removing it altogether solved the issue!
Thank you for your help with this I really do appreciate it - its always so obvious when you finally get to the bottom of it. A good learning experience I suppose
What I need to do now is find a login/authentication system that works natively with CI.
Thank you again
