Arrows Still Not Working.

The arrows are still not working for me. I have tried all the suggestions: Disconnected all plugins, other than the calendar AND at the same time used WP default themes. Did not work. In fact, since this the current month had a previous month and a future month, for the first time, I now lost both left and right side arrows. At that point, I stopped trying to debug it because my life has gotten pretty crazy with my Mom in and out of the hospital.
