While writing a new post, I get prompted "Session expired. Please log in again. You will not move away from this page.". After entering my credentials, the prompt closes and appears instantly again. I've tried both enabling "Remember me" and leaving it unchecked but none of the both works. How can I proceed editing my blog post without losing the data I already entered?
Thank you very much in advance.
The blog I need help with is gammagamification.wordpress.com.
