Internal Error (Captcha)

Hi Folks,

 

i added a CAPTCHA Configuration with google recaptcha to the logon page item with the help of the guides provided here on devC. But as soon as i acces the logon page i get a

 

Message displayed beneath the Username/password fields.

 

I dont have any clue what causes this error and don´t see a way to monitor/check because it does not appear in the log files (/var/log/apm)

 

Anyone got a hint on why/where this error occurs and how to find out whre i can get some info about it ?

 

Regards!
