I have version 3.9 of joomla, OS Property 3.17.2. recaptcha version 2.0 invisible.
In the contact form when sending I get an error "Empty solution not allowed, Invalid field: Captcha". I install the plugin "extensions.joomla.org/extension/mootools-enabler-disabler" as indicated and it works, but the banner on the main page OS Property 3.17.2 disappears if it is activated and appears if I deactivate it but the recaptcha error appears again
