There was a problem with the MySQL Query: UPDATE supertracker set last_click='2021-10-19 23:33:31', exit_page='/5.2_Features_of_'well_formed'_signs-i-451.html', num_clicks='78', pages_viewed='', properties_viewed='' where tracking_id='682979'
The result was : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'well_formed'_signs-i-451.html', num_clicks='78', pages_viewed='', properties_vie' at line 1
