CSRF validation failed - where could be a problem?
This is a duplicate of already asked problem, but I cannot reply or communicate, as I have no carma here and I need some upvotes.
I have seen the problem in an signup form, as only one user in 5 minutes could signup. I could bypass the problem by making my own lead contact module and disable the cache on the request definition. After the changes, the signup rate rises up to a normal level.
Has someone used the crm_lead form without the csrf problem?
