Posts not publishing

Over the last couple of days I have occasionally been prevented from publishing posts. I get a Javascript message saying “Failed to post. Please try again”. Trying again does not resolve the issue.

This happened to me two days ago, also in the evening (UK time). I left the post unpublished in the browser and it published okay the next morning. It happened to me again just now, so I don’t know if the timing makes a difference.

I normally create my drafts as Posts before moving them to my Blog so I don’t know if this would impact publishing directly to my public blog.

This is different from the ‘you’re publishing too much’ behaviour which I occasionally get.

Additional info: I thought I’d try if I could change the publication date of the post by setting it to ‘Now’, and not only did that work, but it also enabled me to publish. Not sure why that would make a difference, but I thought I’d report it.
