please provide a minimal example displaying the problem. There can be a
number of reasons, so it is a lot easier for us to help, is you show
some code.

Please remember that this DOES NOT WORK:

\begin{align*}
f(x) ={} & \left[   blah blah
\\
+ blah balh \right]
\end{align*}

you cannot have a \left and a \right on different lines like that. In
this case one would have to scale the []'s by hand.
