Hello,
Generally, when we see this kind of issue, it ends up being a theme or plugin conflict. Unfortunately, since the linked website is not publically accessible, we won’t be able to view the issue to see which plugins/theme is installed.
We recommend taking a backup of your website, understanding how to do a restore, and installing the WordPress Health Check & Troubleshooting Plugin. This plugin will allow you to disable all plugins except the necessary Contact Form 7 & ReCaptcha v2 for Contact Form 7, along with reverting to a default 20XX Theme. For more information, we recommend reading their documentation, it’s a very nifty and helpful plugin!
Once you’ve verified that the plugin works on a default install, you can enable your theme, then the plugins one by one until you find the culprit. Otherwise, if you’ve completed the above and continue to run into issues, we recommend double-checking the installation guide.
We were able to install the VW Maintenance Services Theme from the theme repository and were able to view the form and reCaptcha as expected.
Hopefully, with the above, you’re able to narrow down your issue to a specific plugin. Once we know which plugin is causing the issue, we can reach out to their developers or build around the issue on our end. Otherwise, if you can provide any other information to help us narrow down this issue, please reply back to this thread. Have a wonderful rest of your week!
Thank you for your prompt reply and detailed information’s. We have changed the Captcha thingi to another solution for now. I can’t promise that we have time to change it back and testing it out.
Anyway, thank you again for your detailed information’s and prompt reply.
Best regards
Gerald
