Jive is the software that runs the forums. I know it looks for profanity, etc.
But once I got the same message you did and kept deleting things until it took. It could be just Jive being Jive.
Can you reword the message?
You can edit until someone else posts, so you could also try doing it in parts. Try one paragraph, post, edit, add the next, etc.
Report back here with the link and what happens so we can report it. (I am assuming your message there is nice and not vulgar!)
Thank you, jane-e. Unfortunately question I was posting is quite long and complex, even after my efforts to make it as synthetic as possible. I was hoping that Jive could show me what wasn't good. But if it's not possibile, I'll try what you suggested.
Yesterday I had the same trouble in the Photoshop forum. Today I was able to post.
If you think all the words are okay, copy it to Word or Email or something and trying again another day.
