Contact Form 7 v5.1 dropped support for reCaptcha v2 along with the [recaptcha] tag December 2018. This plugin brings that functionality back from Contact Form 7 5.0.5 and re-adds the [recaptcha] tag.
Contact Form 7 v5.1 dropped support for reCaptcha v2 along with the [recaptcha] tag December 2018. This plugin brings that functionality back from Contact Form 7 5.0.5 and re-adds the [recaptcha] tag.
If this plugin is installed before updating Contact Form 7 from v5.0.5 to v5.1.1 then it will carry over your old API keys. At that point you will just need to head to this plugins settings page to tell the website to use reCaptcha v2.
Once installed and configured it should be the same reCaptcha functionality you are used to in previous versions of Contact Form 7.

Thrive Comments is the newest alternative to the native WP comments. It’s a WordPress plugin that will bring a whole array of previously unavailable features to your WordPress comments.
The main difference between Thrive Comments and Disqus is the scope of the programs. Since Disqus is part of a universal, multi platform network, it adds some interesting functionality, as well as a few constraints.
The Disqus system outsources comments to their network, so while the comments appear on your website, everything is controlled and hosted on the Disqus network.
