I've got a problem with importing images from the existing folders and wonder if someone can help me on this. Here are the steps, 1) I click on File & Images, then select a folder for example called Uploads, 2) I choose 'Add files to Uploads' button, it will ask me to upload from my computer or import from an existing folder. 3) When I try to import an image from an existing folder, the message - "SecurityID doesn't match, possible CSRF attack." comes up, and I can't go any further.
I've never experienced this before, and wonder if someone can point me to the right direction to solve the problem. I can copy some code here if you let me know which part, and I'm using SilverStripe 2.4.1
