I recently upgraded to 4.1 from 3.3 and it all seemed to go pretty well. I upgraded into a separate directory so as not to overrwrite my 3.3 MT folder. I originally also created a clone of my blog so that I could play around with refreshing and modifying the templates.

However, I soon discovered that I had lost the ability to actually post an entry to either the old blog or the new one. Whether I'm using the 3.3 version, the new 4.1 version or the clone of the 4.1 all I can do is write an entry and save it as a draft.

I can't seem to find any info on the web to explain what I might have done wrong here and I've gone over all the settings trying to figure out what I might have missed.

Any ideas?
