ChronoForms5 5.0.15
Joomla 3.7.4
PHP 7.0.16

I have 3 same forms, in three different language versions, Polish, English, Russian. Most likely, after updating the Joomla version to 3.7.4
The English and Russian versions after filling and clicking send do not report any error and are not sent. There is no thank you message. What could be the reason?

I have such posts in the article
{chronoforms5}formularz-kontaktowy{/chronoforms5}
{chronoforms5}formularz-kontaktowy-eng{/chronoforms5}
{chronoforms5}formularz-kontaktowy-ru{/chronoforms5}


When I call formular directly from components -> Chronoforms5
everything works !
