I currently have ckeditor 3.6.2 installed and working using tep_draw_textarea_field by passing class="ckeditor" as one of the params. Is tep_draw_textarea_ckeditor() part of another addon? Also, my host is running PHP 5.3.27.
Thanks
FYI
Received the following error message in categories.php:
"Fatal error: Call to undefined function tep_draw_textarea_ckeditor() in categories.php on line 751"
I changed 'Enable HTML Editor for Products Descriptions' to false to avoid the error message.
Installed Header Tags SEO 3.3.1 in osc v2.3.3.4.
Thanks
