Hi Gideon, there are 2 plugins calling qa_cookie_get_create():
1. Badges plugin:
- in qa-plugin.php, function qa_badge_award_check, line 261.
- in qa-badge-check.php, function award_badge, line 628.
2. WYSIWYG CKEditor plugin
- qa-wysiwyg-upload.php, function process_request, line 124
I guess it is not caused by HTML but by an error message that must be "triggered" somewhere before.
For the badges the chance to have an error might be the sql queries from line 245 (qa-plugin.php), or calling the function award_badge (happens on different spots).
For WYSIWYG the only chance to have an error is qa_get_logged_in_userid(), see line 123 of qa_get_logged_in_userid.
PS: I still have to update the badges plugin to the latest version. I would like to know from others if they get this php error as well, even with the latest version of badges...
