Cache cleared. Stop no words. What is the problem?

In default configuration, this message appears when there are validation errors. On the other hand, orange-border means there are spam activities detected. The two matters are conflicting with each other.

Also, you are using a Russian (ru_RU) contact form so seeing English messages is weird.
