Nope, sometimes it takes hours... it can be a bit frustrating, but you just need to be patient...
It was probably during the website updates. That happens sometimes.
Miss Veronika is working on the websites. Anytime she makes a change, the server that hosts the website has to update the files. Sorry. One thing I do is write the post, select all of it and copy it to the clipboard. Then when it errors out, I have only to paste it in and try again.
I started to post at 9.30 and now finally at 17.50 it worked...
