I wanted to use the chi squared test on some data, but I have some categories which have a value less than 5. Also some of the expected values for some categories are zero. What can I use instead?

Fisher's Exact might work but only if this module is installed.
As far as alternatives to overcome the small case count, there isn't. Know that this is a warning and doesn't mean that the chi-square results is wrong, only that "use with caution."
