[Support request] WordPress 5.5 update – Issue with Landing theme

[N]

Hi,

There appears to be an issue with the Landing theme and the latest WordPress update to version 5.5. I get this error message on the header of the homepage:

Notice: rest_validate_value_from_schema was called incorrectly. The type schema keyword for can only be one of the built in types: array, object, string, number, integer, boolean and null. Please see Debugging in WordPress for more information. (This message was added to version 5.5.0.) in /home/customer/www/exclusiveaesthetic.uk/public_html/wp-includes/functions.php on line 5225

Hi there,

test to see if there is a plugin conflict by temporarily disabling all other plugins. If the issue is resolved, re-enable them on by one to see which is causing the error.

I reinstalled the previous version, WordPress 5.4.2, and the error message is no longer there.

Before changing the WordPress version back to 5.4.2 I disabled all plugins and there was no change to the code, it was still visible.

Hi David,

Thank you for your email. I tested this on another site, it appears the HappyForms plugin was the cause. I’ve contacted HappyForms about this. Thank you for your help.

Glad to hear you found the issue – and thanks for sharing the problem plugin. Seems there are quite a few plugins that are can’t primed for 5.5

Hope they resolve it asap.
