Thank you for your quick response!
I'm working with osCommerce 2.3.4. So, I'm good there.
Now I'm getting this error:
1364 - Field 'date_added' doesn't have a default value insert into configuration ( configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, use_function, set_function ) values ( '', 'MODULE_HEADER_TAGS_THEME_SWITCHER_JQUERY_TEST', '', '', '6', '7', 'tep_jquery_check', 'tep_cfg_do_nothing(' ) [TEP STOP]
Thank you for your help. I realize you haven't had to modify your module in a while. I sincerely appreciate your support.
