Occasionally Firefox and Chrome users cannot login to our OMERO server and receive an error message that looks like this:
CSRF Error. You need to include valid CSRF tokens for any POST, PUT, PATCH or DELETE operations. You have to include CSRF token in the POST data or add the token to the HTTP header.
Has anyone else seen this? I have been offering users suggestions for clearing their browser cache and deleting any omero cookies or csrf tokens. This helps sometimes. Usually people switch to Safari trying to fix the browser fails to resolve the problem.
What I would really like is to find to root cause of this and fix it permanently, if possible. I would appreciate any suggestions for how to troubleshoot and fix this.
