Problem with comments and recaptcha

I get two jquery errors on every page with a comments area for example here: http://www.ahdesign.de/leistungen/item/405-webdesign . You will find the recaptcha div in the source code and in firebug as well. But you do't see it at the page!

The recaptcha is configured right and works without any problems for example here: http://www.ahdesign.de/impressum or here: http://www.ahdesign.de/theme-features/registration-form or here: http://www.ahdesign.de/theme-features/username-reminder or here: http://www.ahdesign.de/theme-features/password-reset !

Have you any idea?
Greetings Overtone

Has nobody this problem?

I have some news for this problem. Somtimes the captcha appears, but when I send any comment a blank page opens with messages like "{"message":"Ung\u00fcltige E-Mail-Adresse!","cssClass":"k2FormLogError"}". Here is something wrong with the javascript. I just turned of the reCaptcha, but the problem stays!!! So it is a problem with the comment form in an article!

P. S. In the contact form at http://ahdesign.de/impressum everything works perfect with or without reCaptcha!

I found out the solution: In the K2 params the settings for the jQuery library handling (tab "Layout & Views") is "Do not load the jQuery library" by default!!! After I changed this to "Load v1.12.1 (local copy)" everything works perfect!!!

Hi

Thank You for shearing this with us, but it may not work for everyone. If joomla is set to use it's library it may come in conflict. So if someone will use Your solution and it would not work I advice to use Easy jQuery to force a load of only one jQuary library at a time.
