I was able to reproduce the CSRF attack error that was talked about in another topic.
The suggested workaround in that topic didn't work for me either, but something else did.
I'm using Firefox, by the way, that might make a difference here - I don't know.
So, sometimes I go to write a new article, and a draft of an old article is in the editor.
When this happens, I am going to get a CSRF error when I publish my new article. This has happened a couple times now.
Save the article outside of Erepublik - anything you type is going to be lost when you do this.
Hit 'publish article'.
You'll go to the CSRF attack error screen (or you'll publish the article, that would be even better).
Then, go to your address bar and click on it to highlight the address, and then hit 'enter'. This will bring you back to the Write Article screen, but with no text in the body of the article (or title either, for that matter). Basically you reset the article page, I guess. Then, copy and paste back in, and voila! Publish and it works. This has worked every time I've done it, and I hope it works for you too.
Happy publishing!
