It just keeps saying that the captcha is invalid when using the plugin.

Check if you have not setup also osclass built-in captcha and that you have captcha badge in form.

Yes i only setup 1 and yes I can see the captcha badge. But still dosnt work.

That is impossible.
Send screenshot from osclass settings, plugin settings and url

Only the recaptcha plugin is active. The osclass spam bot is not active. But the captcha keeps saying error. kohchang(.)asia

Then you have probably not added recaptcha code to specific form. Do you see it in front?

I can see it in the forms yes. Its just gives me an error all the time saying its not completed the captcha correct. The only thing I can think of is I am using cloudflare, could his be a problem?

Not sure about cloudflare, send url

https://kohchang.asia

Thanks

you have something wrong there.
not sure if it is not in conflict with pwa as well, try to disable and test.

I have not changed anything else. All I have added are the plugins that we purchased.

I tired to disable PWA plugin but Captcha still doesn't work. Ive been trying for over a week and there is not else available on google for help.

Or if this doesn't work is there any other solution to add a simple captcha without using the plugin?

No as it would only be front-office integrated.
