I cannot post or update posts or pages after a new wordpress installation and an import from a tumblr site
( via Tumblr2WordPress: Export Your Tumblr To WordPress http://haochen.me/tumblr/ first I made the file through this site and after that I imported via the option 'Install the WordPress importer to import posts, pages, comments, custom fields, categories, and tags from a WordPress export file.' )
I can only post for review, while I am the only user and of course I am admin.
What happened? And how can I fix it?
