I had exactly the same yesterday, which was odd as the only writing to Twitter I do is via Facebook a few times a week. When I went to (https://apps.twitter.com) there was a red restriction notice on it. But I noticed that a Facebook post this morning had been tweeted so I checked at (https://apps.twitter.com) again and the restriction notice had gone. So maybe just a glitch at Twitter’s end?
Hi. I had exactly the same problem. In the end I stopped using Libreoffice and used Excel instead. I also copied the sample file and just inserted my own data under the post_title post_content etc. headings. Then it worked fine. I hope this helps.
