@codepeople I have the same (?) issue after the latest update of the plugin. How can I send you the link to my page in private?
Downgrading to 5.3.2 seems to be the best solution I have found so far.
You can add a span class and css.
On the form:
E-Mail <span class="required">(required)</span>
Add CSS:
.required{
color: #ff0000;
}
I have the exact same problem. This needs an urgent fix.
WP_DEBUG is disabled (false) when this error comes up.
Same result on enabled.
