Cannot save changes to contact form – bad URL

Hello,
I have a weird error… saving settings on contact form 7 fails because after clicking SAVE it tries to go to the URL
site.com/wp-admin/site.com/wp-admin/rest_of_the_URL …

Specifically:
http://site.com/wp-admin/site.com/wp-admin/admin.php?page=wpcf7&post=96&ip-geo-block-auth-nonce=7807fc4ce7

The problem is in conjunction with https://wordpress.org/plugins/ip-geo-block/ …disabling that makes it go away. I’ll cross-post the issue there.

Something I saw in the page source, not sure if it’s related:
<form method=”post” action=”//site.com/wp-admin/admin.php?page=wpcf7&post=96″ id=”wpcf7-admin-form-element”>
… it seems like the http: is missing in the form action?

The save buttons have this:
…the one in the right sidebar
<div id=”publishing-action”>
<span class=”spinner”></span>
<input class=”button-primary” type=”submit” onclick=”this.form._wpnonce.value = ‘d09deaa29e’; this.form.action.value = ‘save’; return true;” value=”Save” name=”wpcf7-save”>
</div>

…the one underneath the form
<p class=”submit”>
<input class=”button-primary” type=”submit” onclick=”this.form._wpnonce.value = ‘d09deaa29e’; this.form.action.value = ‘save’; return true;” value=”Save” name=”wpcf7-save”>
</p>

I’d appreciate any help…
Thanks
Nils
