Perhaps refreshing the page might be useful.
Outside of that it's worth checking you're using a modern browser & that your browser is up to date.
I've used safari & google chrome and have had no issues using the Steemit website so far.
Hope this helps
Thanks for your response, I am using an ipad air2 mostly. It only seems to be my post that sticks, I habe read many articles from other people. I'll see what happens.
