Deleted database tables and installed the latest version. I can update the polls but preview is still not showing.

If no error message shows up, then the only way to figure out is tracing the code.

The problem could be a certain php configuration. The last one I encountered about three month ago is that the user was using an old php switch that was popular 10 years ago but no longer recommended by the php maker.
