"badcachekey" error from API after 1.27 > 1.28 update

Hi, after successfully using Mediawiki 1.27 with VisualEditor for a while; we wanted to upgrade to the newest version because the editor starting to show some weird problems.

So I did an upgrade to Mediawiki 1.28, VisualEditor-REL1_28-93528b7 and Parsoid 0.6.1.

Now an error message occurs when saving a page which says "Unknown error". However the page does get saved. If you look at the 3 POST requests (to api.php) made by the save actions 1 fails (the 2nd one). It returns an error object with code "badcachekey" and info "No cached serialization found with that key".

If anyone can help us by explaining why this error occurs and/or what we can do to fix it, it will be greatly appreciated! We're kind of at a loss since downgrading doesn't seems to be possible?

Versions: MediaWiki 1.28.0 PHP 7.0.8 (apache2handler) MySQL 5.7.13 ICU 52.1

I can confirm this issue. Currently running WAMP Server 2.5 (wampserver2.5-Apache-2.4.9-Mysql-5.6.17-php5.5.12-64b) with Mediawiki 1.28.
