[Resolved] Unable to post comments on Dutch part of website when using a subdomain for it

Hello

I just tested this in my local test system setup with domains-per-language and was unable to reprdouce the problem.

I also connected to your site and confirmed that the problem exists as you described.

Could you please confirm that this same problem happens if you temporarily change your active theme to Twenty Seventeen and also temporarily deactivate you non-WPML plugins?
(In this case, your setup will be the same as my local testsite and we can then discard server-related issues).

As a preliminary diagnosis, I can see that there is an error reported when attempting to post the comment in the NL language of the type:
"Access to XMLHttpRequest at 'hidden link' from origin 'hidden link' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource..."

So it seems a problem of cross-domain permissions but it is not clear if this is being caused by our plugins, another plugin or by your theme.

I will be investigating if there are any reported errors of this type while you do the diagnostic tests as requested.
Thanks

Yes. That is what you should do until you find which plugin is causing the issue.

Congrats! Ok - should we keep this ticket open or close it?
Maybe if you decide that you need this, we can open a compatibliity ticket for further investigation. IN this case, let me know and I will create a sandbox site where you can load up the plugin and we can recreate the problem to then send it on to our compatibility team.

I`ll leave it up to you.
Kind regards

Ok.

I have prepared the following sandbox site wiht pre-loaded/pre-configured WPML plugins.
Please now upload the Bruiser plugin and configure an example that illustrate the incompatibility we have discovered.

Once this is done, I can then send it to the comaptibility team.
Thanks

Hello

I have been given a "fix" that I´ve tested on the sandbox site and it seems to work. Please go ahead and test there.

The fix is the following.
Replace line 65 in file: wp-content/plugins/goodbye-captcha/engine/modules/GdbcBasePublicModule.php

with the following line:

$clientUrl = esc_attr(esc_url(site_url('/', MchGdbcWpUtils::isSslRequest() ? 'https' : 'http') . '?gdbc-client=' . GoodByeCaptcha::PLUGIN_VERSION . '-'));

This is essentially the same line but with the "home_url" being replaced with "site_url".

If you are satisfied that it fixes your situation, please go ahead and implement the fix on your own site. You should also notify the plugin author about the fix and be aware that if you upgrade the plugin you may overwrite the fix. The ideal situation is that the plugin author will include the fix in the next plugin release.

Kind regards
