Every time I try to leave comment on a content of a certain type I get this error:

Validation error, please try again. If this error persists, please contact the site administrator.

Refreshing and resubmitting the comment manually does not fix the problem, I always get this issue. The content type in question is displayed via a Panels Node Template, if that matters.

1 Answer 1


I traced the problem down to the the panels pane that displayed the comments list. If the comments list was disabled, comment submission worked fine; turned back on the validation error returned.

Looks like this is caused by a (likely) bug in CTOOLS. The patch in comment #1 fixed the issue.
