I can publish a post if I use Plain permalinks or use classic editor, but both of these options do not work for me

Thank you, Sahil for the suggestion. I have tried it and it did not help with the issue

Try to log out and login to backend again.
by the way I was getting the following error:
PHP Fatal error: Call to undefined function is_plugin_active_for_network() in /rss-image-feed/image-rss.php on line 271

wp 3.8 and 3.8.1 started showing white empty page after plugin update on 25 of March. Deactivated the plugin and problems disappeared.
During white screen problem found that redirections stopped working like from non-www url to www url

I have updated wp (3.8) and got token without any problems

thanks
