Please enable the "Use WordPress native AJAX functions" option, it should work fine. The option is located in the Dashboard > wpDiscuz > Settings > General Settings tab. More info here: https://wpdiscuz.com/docs/wpdiscuz-7/plugin-settings/general-settings/#use-wordpress-native-ajax-functions

Oh no! As they say in Hamlet, "When sorrows come, they come not single spies but in battalions"! I have now fixed that issue and submitted a comment but it has done the same as before.... console error. Thanks for your help.

Hi,

Please first fix the reCAPTCHA error on your website, then let us know.

The reCAPTCHA error message is: “ERROR for site owner: Invalid domain for site key.”

One of my users contacts me to tell me that they couldn't submit a comment and indeed having tried it myself I get the same issue. When I hit the Submit button it does nothing. I get no error message back. There are some errors in the browser console... as below:

4506

Any ideas please? (Sorry, I'll flag up front that I am not very technical).

Thanks, Bob
