It's one wordpress with WPML installed. WPML manages the domains.
We use the plugin: "Contactform 7", and on every domain it working.
The problem is that no contact forms are working at one specific domain: cashdesk-pos.com (EN).
We already tried the following things:
- We tried to disable multiple new plugins
- We've disabled recaptcha on contact form 7
- We've checked if the WP API is working (the default wordpress tools shows it is working)
- Even if we place a form (that is working on NL) on the cashdesk-pos.com domain it won't work (that is the reason why I think there may be a WPML issue)
The error we get is also very general:
{
"code": "internal_server_error",
"message": "There has been a critical error on this website.Learn more about troubleshooting WordPress.",
"data": {
"status": 500
},
"additional_errors": []
}
