Hello,

Please make sure that you are using the latest version of the plugin (it would be best to download the reCAPTCHA plugin again from our site and install it over your current version) and that the keys do not have any blank spaces. If the problem persists after you have checked these settings please submit a ticket to our tech support team.

I had the same issue as this after copying and pasting in the keys, which i know are correct because it works perfectly on my current site.

However, after searching and searching for more info, when i went back in and compared the keys from the current site and the new site it turns out that the public key was missing characters, which i know had been copied correctly, not sure what happened there.

So i recopied making sure everything as pasted in the box this time and making sure both keys matched exactly.

Hey presto it works now, make sure you are copying the keys correctly and once you save them for the first time go back and compare the keys just to make sure everything is exactly the same

I hope this helps

Derek

I think because RSFORM read and store config value into session, so recaptcha cannot read value after you install and config recaptcha plugin. Simple solution's clear session by logout your account or wait to timeout

If you do that and still see "To use reCAPTCHA you must get an API key from recaptcha.net/api/getkey" at the top of the form, and "Input error: k: Format of site key was invalid" please open plugins/system/rsrecaptcha and add RSFormProHelper::readConfig(); before and any RSFormProHelper::getConfig('xxx').
Have a nice day

Hi,

trying to get the ReCaptcha v1.3.0 on RSForm v1.4 to work.

Dok

downloaded latest versions.
RSForm! Pro 1.4.0 Rev 46 and plugs

all plugs enabled
no leading trailing spaces in keys

get error
Input error: k: Format of site key was invalid

same problem

It's very simple: copy and paste the Public and Private Keys in their respective fields from RSForm! Pro > Configuration > ReCAPTCHA. There's nothing else that needs to be done - if the keys are present, without any extra spaces and are correctly copied (please make sure you select the whole key) everything will work as it does for literally thousands of websites.

I had a similar issue but I found that I had K2 enabled on the site to handle form processing and the reCAPTCHA key information was not configured in this section. If you have K2 on your site you may want to check the configuration settings in this area.

I saw 2 plugins. 1 captchawith palce to put keys, and another rsformpro captcha which was disabled. I enabled rsforms pro captcha and put my keys in the first one. This didn't work. after 1 hour of searching the web no luck. Then i went to rsforms configuration and found a captcha tab there. Presto! Put your keys in the correct place everyone!

The Captcha plugin is a Joomla! plugin which has nothing to do with RSForm! Pro. The docs also state that the keys should be added in the Configuration area of RSForm! Pro.
I'm locking this topic since it's 3 years old and lots of solutions have already been presented.
