Looks like that was it, the K2 component. Thanks!

Is this the Registration page http://simracinghub.com/forum/division-2-team-selection? I'm getting a 404 error for that page. P.S. If your using a 3rd party plugin do you have the Joomla one disabled?

I apologize and thank you for the answer

Please do not post extensions/template specific questions in the "Free stuff" forum. You should post in the extension forum or template forum as appropriate. Most of these forums are for members who have a current PAID membership. Our priority is always to assist paying members. Thank you for your understanding. You subscription expired many years ago. Support does require a current subscription. Please ensure that everything on your site is up-to-date - Google changed the recaptcha API a while back and that forced joomla to fix this in a later version of joomla. You also didn't post a link so there nothing for me to check in any case? - look in browser console too for error messages. Regards, Mark.

Thanks so much! I'll try it out! :)

Please would you post your URL, superuser id and pswd in the secure tab of your post and i'll have a look for you. Also attach a screen shot of your google recaptcha keys on google. Regards, Mark.

I have configured (apparently incorrectly) recaptcha v2 on my Gantry 5 contact form (a particle). I see this error message when I submit the form: recaptcha__en.js:372 Uncaught TypeError: Cannot read property 'pN' of undefined at recaptcha__en.js:372 at mootools-core-compat.min.js?ver=5.6.2:2 at Array. (recaptcha__en.js:116) at F1.zU.render (recaptcha__en.js:659) at Array. (recaptcha__en.js:10) at Array. (recaptcha__en.js:9) at rr. (recaptcha__en.js:40) at new rr (recaptcha__en.js:536) at Array. (recaptcha__en.js:126) at recaptcha__en.js:193 Can anyone tell me how to fix this? Thanks in advance.

Hi guys, I'm a great problem with my registration form. I'm installed Joomla 3.4.0 properly and now when I try to test the registration form and insert all correct information, included the captcha code, I receive an error like this: "empty solution not allowed". I haven't changed any parameters on admin panel. How can I do to solve this problem? Thanks in advance Best regards

Well, it is normal that your registration page just reloads since your recaptcha is not working correctly. You will have to deal with this issue and I strongly suggest you to post a question on Joomla official forum regarding this

what do you really want your blog to do that joomla can not out of the box ? Nested categories, ACL/permissions to prohibit bloggers from posting in certain categories, comments, tags, recaptcha, videos, ajax, user/blogger pages, custom forms and fields, to name a few. ;)
