After upgrading from WordPress 3.7.1 to 3.8 and CF7 from 3.5.4 to 3.6, the related "Contact Form 7 BWP reCAPTCHA Extension" plugin stops working; instead of showing a reCAPTCHA, it only shows the [recaptcha recaptcha-xxx] shortcode.
In attempt to fix this, I replaced the BWP extension with "Contact Form 7 reCAPTCHA extension," and the exact same problem occurs.
My (temporary) solution:
When I deactivated + uninstalled CF7 and re-installed CF7 version 3.5.4, the reCAPTCHAs started working again.
I've had this problem occur on 3 separate WordPress sites.
I'm guessing this will have to be remedied in the next version of CF7. It's quite odd to me that two recaptcha extension plugins would both have the same problem, which is what is leading to believe it's a problem with CF7. I have posted on the other plugins' boards too though, looking for answers.
Any information would be appreciated. Thank you!
