The front end of my site displays this message:

145 Table './shocking_catalog/whos_online' is marked as crashed and should be repaired
in:
[delete from whos_online where time_last_click < '1210125508']

I followed the instruction in the Zen-Cart Wiki to fix the table. I opened phpMyAdmin, clicked the SQL tab and entered the query "REPAIR TABLE whos_online" then click "Go". After I did that, nothing has changed, my site is still showing the same error message. What am I missing?

I am still able to log in at the backend though.
