Hello again, but with a little bug

Hello everybody, I just returned home after my summer holydays (3 weeks on the beautyfull shores of Adriatic Sea, near the city of Ascoli).

I write not only to justify why I didn't post anything in 3 weeks, but also to say that I had a problem with my smartphone and my tablet: I was able to read outofcards, to write under the comments, but apparently when I used the button to publish my post nothing happened.

Has anyone else had this problem, or it was just mine?

Both are android based and I use a browser based on mobile firefox.
