Thanks Greg, I added the permission "edit all" to the Administrator and I deleted the unwanted text from the post, as you said. I'll think of how to explain it to my users. I would like to take this opportunity to congratulate you on the support forum. You are very kind and, above all, give me the answers always and immediately. I tried several forums before choosing Nabble and I'm better here, even though I am Italian and sometimes I do not understand what you write, and I'm not very good even to write (I still use the translator
). I wish you all a beautiful day.
