i have upgraded CA from 4.6.0 to 5.0.1.
when posting a new question as a guest user (not logged in) i see this error after submitting the form:
0 Argument 2 passed to Joomla\CMS\Application\BaseApplication::triggerEvent() must be of the type array or null, string given, called in /mnt/data/vhosts/casite-710858.cloudaccess.net/httpdocs/components/com_communityanswers/models/form.php on line 142
and the question is not posted on the site.
on version 4.6.0 the guest users had no problem posting questions.
by the way - there is no problem posting replies as a guest user.
