Not working – 500 Error

Hello! We are facing an issue, and I’ve seen we aren’t the only ones. So I’m providing more info in case it helps; Forms are not sent.

We have version 5.7.6, but also tried to rollback to 5.7.5.1, 5.7.5 and 5.6.4 and the problem is still there.

The message we are getting on the console is:

===

XHRGET
https://www.fls-science.com/wp-json/contact-form-7/v1/contact-forms/4846/feedback/schema
[HTTP/1.1 500 Internal Server Error 425ms]

Uncaught (in promise)
Response { type: “basic”, url: “https://www.fls-science.com/wp-json/contact-form-7/v1/contact-forms/4846/feedback/schema”, redirected: false, status: 500, ok: false, statusText: “Internal Server Error”, headers: Headers(13), body: ReadableStream, bodyUsed: false }

We have auto-updates enabled, so I’m not sure what plugin could cause it.

We use several plugins, some I’ve seen in the forum causing issues are Conditional Fields and WooCommerce.

We tried desactivating WooCommerce and several related plugins and didn’t solve the issue. Also Conditional Fields. No luck. I’ve deactivated the plugins that were updated in the last couple of days, and still have the problem. I can’t deactivate Polylang though…

I also noticed that the .htaccess file in the root directory was changed.

Thanks a lot for your work!
