"Tweet sent" but not posted on Twitter

Now I reinstalled the plugin, I get the message about database update and it is still working.

Anyway, it does not post to twitter yet

What do you mean when you say “I just tried to get a new api / secret key but nothing happens.”?

I read that sometimes getting new apis helps in fixing the problem, but it’s not my case.

Everything is ok but posts are not published on Twitter, and no error is shown

OK; I thought maybe you meant that you weren’t able to get a new API or secret key.

If there’s no error, that suggests that for some reason your posts are meeting the criteria for some filter that prevents them from Tweeting. Have you made any changes to your site recently, such as changing servers or adding a new plug-in, etc.?

I’m assuming that you’re not currently allowing edited posts to Tweet; can you turn that option on and test whether those work?

Hi, the only working function is when I tweet manually. Automatic posting on Twitter does not work at the moment, and I continue getting the “database upgrade message” which never stops.

In addiction to the previous message, when I perform a test tweet, it works. When I tweet manually, it works. When a post is planned, or when I publish directly, it does not tweet. I think it could be related to the database update, but even if I click on it, the page becomes white and it seems to be stuck without working.

It’s not related to the database update; the only thing that effects is whether re-Tweeting old posts will use the same short URL it did the first time they were Tweeted.

You’re not getting any error message at all, then, when you publish a post?

No error. It simply does not tweet.
