We were getting this same error on our ecommerce site after adding Kadence buttons to our Terms & Conditions page, which gets added to purchase emails but isn’t loaded in the browser to the end user. Those emails weren’t being sent and we saw the Fatal Error described above in our logs.

That page loads fine in a browser, but it seems that if a page with a button is loaded/parsed in a certain way Kadence’s internal logic gets tripped up if a custom class name isn’t added (line 3: /blocks/class-kadence-blocks-singlebtn-block.php(243): get_block_wrapper_attributes(Array) #3).

By adding a custom class to the button we were able to make this error go away (under Advanced>Advanced, Additional CSS class(es)). Hopefully this helps someone else and perhaps even gets the Kadence folks to fix this bug (??)

Will do, thanks for the speedy reply!

Perfect, thank you so much for the help and the great plugin.

Thanks. After disabling WP Super Cache, I’m able to submit forms. Does this mean WP Cerber and WP Super Cache are incompatible? Is there another caching solution that will work with WP Cerber? We do need to have our site cached; if you can provide some work around or solution that would be great.
Thanks in advance.

Thanks Gioni, I just sent the information along.

Thanks. I didn’t have POST fields saved, so I sent another test form submission through after activating. Masking the email address as it’s a real address.

Sure thing.

The first four requests are me testing various form entries. The next two are a customer of ours trying to get in touch. The next ones are spam (as far as I can tell).

Let me know if you need more information.

Apologies for the typo in the title of this request ??.

Is there any guidance on how we can block spam on these forms without blocking everything?

Thanks!
