If you deactivate it, it obviously stops any interaction. (If you used manual insertion method, you really want to delete <?php echo spr_show_rating();?>
where ever you added it. Quite obvious thing). Deactivation/Activation is handled by WordPress itself. I have no clue what you did there or what even caused your problems. I can’t read your mind you know. One thing I’m sure of – it wasn’t caused by my plugin.
Also, if you have any suggestions like “what you wanted with a rating system”, feel free to let me know .
