When I run update.php on my Drupal 6.22 site I get the following errors:-
* warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 24. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 25. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 26. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 28. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 29. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 30. * warning: Attempt to modify property of non-object in /var/sites/g/globaloptimists.org/public_html/modules/date/includes/date_plugin_display_attachment.inc on line 31.
What do I need to do to fix it? It doesn't actually seem to break anything at the moment.
