This has now been resolved, it turned out to be my fault!
I’d managed to nest my form tag within another, blank form tag. The browser then ignored the inner tag.
If anyone knows what is going on here it would be much appreciated. All I have is a <form … tag in my theme for searching the page and something is stripping off its arguments so that it is interpreted by the browser as <form>
Any ideas?
Thanks
