warn: [socket.io] Empty method name

[codecowboy]

I'm getting this error in the nodebb log when I try and create a new post/topic:

warn: [socket.io] Empty method name

I recently moved the forum between servers. When I hit submit on the new post/topic, the submit button dims to a lighter blue and becomes disabled but the post is not created.

Does anyone have any ideas how I can troubleshoot this further?

I am using the redactor composer v 1.3.6. NodeBB version is 0.9.0 (I plan to upgrade soon but would like to fix this first)

composer default is disabled - I have a dim memory that this was required in order to use the redactor composer.

Would be grateful for any ideas on what might be causing this as I am crying into my cornflakes
