I am using CiviCRM 5.9.1 and Drupal 7.6
I am creating a new event. adding the image to it by using CKEditor. when I tried to browse images/ upload the image. The error is coming. Please refer to the screenshot for the error.
I followed the previous question regarding this KCFinder. I applied the available patch that is for civi 4.6. That one also didn't work.
I checked file permission and drupal uploading file permission. It is fine.
Please give suggestion how to solve this issue.
