[wp-hackers] set_transient returns false on live server but true on local host.

[Haluk Karamete]

What would be the reason for the set_transient API to return FALSE on a
live server but TRUE on local host - that's obviously for the same code.

The only diff is live server is IIS and the local is Apache.

And how would I get to the bottom of a set_transient-returns-FALSE
situation?

I understand that the set_transient does not return an error object in the
case of something not going right.
