lang
Type

Recaptcha is very good in automatic detecting which language to use based on the users browser settings and with which IP the page gets visited. Only in case if it is really necessary set this parameter to take influence on the rendered language.

enforceCaptcha

enforceCaptcha
Type
string
Default
0

This configuration parameter will enforce the captcha to test the functionality on development systems. EXT:recaptcha uses the application context to detect if an installation is running in Development mode. If so the captcha is not rendered or validated. This is a to reduce external calls and b to not bother the integrator every time he has to test forms. Because after a limited amount of tests the captcha testing games must always be solved instead only clicking a checkbox.
