Freeform form expired in one browser

Question

I have a basic Freeform contact form that works in Chrome but not Safari, due to:

This form has expired. Please refresh and try again.

If I clear the EE cache and try again from Safari, it works fine. If I then try Chrome I get the above error.

I have tried using:

input type="hidden" name="XID" value="{XID_HASH}"

...But this doesn't work. I have also tried turning off secure forms in the config:

$config['secure_forms'] = "n";

...And this has no effect either.

There's another form on the site which is very similar, and I have no issues with it.

Any idea what the problem could be?

EE 2.10.1 Freeform 4.2.4, though issue was found in 4.2.3.

Answer 1

I've seen this issue with the native email form, that was caused by the domain name not matching what was set in General settings.

So if your site URL/domain setting is www.example.com (with www) and you access the form page using example.com (no www) that can give the error.

The solution is to ensure the domains match. If necessary add a .htaccess rule to make sire the page redirects to the appropriate version, www or non-www.
